Penjelasan tentang Modulasi PWM dan Modulasi FM Menggunakan Proteus
Summary
TLDRThis video script discusses two types of modulation: Pulse Width Modulation (PWM) and Frequency Modulation (FM). The presenter uses Proteus software to simulate both modulations, explaining the process and components involved. PWM involves varying the pulse width while keeping the frequency constant, demonstrated using a diode, IC555, and other components.

Outlines
😎 Introduction to PWM and FM Modulation
The speaker begins by greeting the audience and introducing the topic of modulation techniques, specifically Pulse Width Modulation (PWM) and Frequency Modulation (FM). They mention facing a challenge from the T2Pro clan in the field of telecommunication studies at the Semarang State Polytechnic in 2020. The speaker then explains their intention to use the Proteus application to simulate both PWM and FM modulations. They describe the components used in the simulation, including a diode, transistor, IC555, capacitors, potentiometers, resistors, and a voltage source. The speaker guides the audience through the process of setting up the simulation in Proteus, including searching for components and configuring the oscilloscope for clear signal visualization. The video is sped up due to the time-consuming nature of the simulation setup.
🔊 Exploring FM Modulation and Its Output
In the second paragraph, the speaker focuses on the output of the FM modulation. They mention that the output signal from the simulation is named MP3 Tiny, which represents the FM signal. The speaker explains that the information signal is obtained from a capacitor, and the carrier wave is derived from another component. They connect this to a PDA, emphasizing that the carrier signal's frequency depends on the voltage in the middle of the circuit. The speaker has successfully simulated the circuit using the Proteus application, and it runs smoothly. They then provide a brief explanation of what CWM (PWM) and FM modulation entail, highlighting that PWM involves changing the pulse width while keeping the frequency constant, whereas FM changes the frequency of the carrier signal according to the information signal's voltage changes. The speaker concludes by summarizing the differences between PWM and FM modulations, noting that PWM alters the pulse width while FM alters both the frequency and period of the carrier signal. The speaker ends by thanking the audience for watching, encouraging likes, comments, and shares, and offering apologies for any shortcomings.

Halo assalamualaikum warahmatullahi
wabarakatuh saya menghadapi perlawanan
dari clan
t2pro di program studi pakai hadapan
teknik telekomunikasi Politeknik Negeri
Semarang tahun 2020 Pada kesempatan kali
ini saya akan sedikit menjelaskan
tentang dua jenis modulasi yaitu
modulasi PWM atau pulse width modulation
dan aksen atau frequency modulation
Kemudian pada pesawat ini saya akan
menggunakan aplikasi proteus untuk
mensimulasikan kedua jenis modulasi
tersebut
Hai berikut adalah rematik
Hai dari modulasi
Hai dari MotoGP WM nah dan yang ini
adalah gambar dari skematik modulasi FM
the lounge
Hai kemudian kita langsung vokal tapi
tapi perutnya dan kemudian kita
bawa ambil komponen yaitu dioda satu
n4007 kemudian 14 box 148 sebagian ic555
kemudian kapasitor ternyata pelet
kemudian ada potensiometer kemudian ada
resistor dan juga ada vetsin versi
digunakan sebagai generator tekanan
dengan cara kita klik huruf p kemudian
kita kita ketikkan nama komponennya
tentu saja kita pengambil restore
kemudian kita klik
the lounge
Hai kemudian kita oke
I Max selanjutnya kita rangkai rangkaian
mobile
Hai sesuai dengan skematik yang
Oke sudah ada
Hai karena mungkin ini membutuhkan waktu
yang lama maka akan saya percepat
videonya nanti
Oh
ya sudah selesai juta langsung trend
saja
hai oh apakah kain serut hasilnya belum
mungkin kita setting osiloskop nya
sesuai dengan yang diperlukan seperti
misal sinyal adanti yang digunakan maka
link-link yang lain kita bagian saja
kemudian kita turun ini bentuknya supaya
sinyal dapat terlihat dengan jelas
Hai seks ini adalah
Hai Elen tuh gelombang dari mobil CWM
atau pulse width modulation
gelombang keluaran itu dihasilkan dari
proses di isinya Nah untuk menemukan
lebar perusahaannya itu dengan menggeser
geser potensi Uni
lalu kita langsung ke scanner skematik
yang berikutnya yaitu
Hai pemodulasi BWF
Ayo kita rangkai sesuai dengan
hai skematiknya
Erna komponen-komponennya sama kita
langsung saja
Hai membuat
orang kayaknya langsung diprotes
mungkin rantai ini akan saya skip karena
memerlukan waktu yang cukup lama
e-learning
ini kalau sudah berhasil kita langsung
Ran saja untuk melihat tak kalau
gelombang keluaran dari modulasi FM ini
MP3 Tiny adalah keluaran dari sinyal FM
hai oh gelombang keluaran Lex pertama
itu sinyal informasi diperoleh dari
ini kapasitor ini
dan untuk gelombang pembawanya itu
diperoleh dari facial dan ribet yang
disatukan kemudian dihubungkan dengan
PDA ini deh
Hai nilai dari
itu apa sinyal pembawa itu bergantung
pada air yang berada di tengah ini
Nah perangkaian sudah kita praktekkan
atau simulasikan dengan aplikasi proteus
dan sudah berjalan dengan lancar
kemudian mengamalkan
hai Sebelumnya itu apa sih yang dimaksud
dengan CWM atau pulse width modulation
dan apa itu yang dimaksud dengan FM
frequency modulation and
hai hai
Hai ke CWM itu adalah
Hai atau bisa disebut dengan khusus
modulation atau berbahasa Indonesianya
modulasi lebar pulsa yaitu sebuah teknik
modulasi
untuk mengubah pulsa
atau lebar pulsa dengan besaran nilai
amplitudo dan
Hai penilai frekuensi yang tetap
paint kemudian
hai hai
Hai
untuk sinyal ya bisa dilihat pada ini
gambar yang karena atau sini Nah itu
bisa dilihat itu
frekuensi dan amplitudonya sama-sama
selam yang membedakan itu adalah lebar
pulsanya dan untuk mengatur lebar
pulsanya ini bisa diatur pada potensio
dalam rangkaian bisa pertama ini
Hai Nah untuk yang kedua yaitu
Hai frequency modulation
frekuensi-frekuensi atau map frequency
modulation atau FM Hai itu adalah proses
menempatkan sehingga informasi ke sinyal
pembawa sehingga
frekuensi pada sinyal pembawa
Hai itu berubah sesuai dengan perubahan
tegangan pada sinyal informasi bisa
dilihat pada gambar yang bawah ini
I love
Hai sinyal yang keluaran ini tergantung
sinyal keluaran ini adalah sinyal
pembawa yang berubah-rubah sesuai dengan
sinyal informasi
bisa dilihat perbandingan dari sinyal
informasi dan sinyal yang sudah
dimodulasi dengan FM
hai hai Hai nah kemudian
Hai Apa yang membedakan dari kedua mobil
jenis populasi tersebut
yang pertama untuk modulasi
Hai itu
deskripsi sudah seperti yang sudah saya
jelaskan tadi
pada modulasi PWM itu frekuensi dan
periode yaitu Selalu sama-sama setelah
tetap yang berubah itu adalah lebar
pulsanya
Hai dan untuk FM frequency modulation
itu
frekuensinya berubah
Hai periode nya juga berubah ini
Saigon Mungkin itu saja yang dapat saya
sampaikan pada video kali ini Terima
kasih untuk yang sudah menonton
Hai jangan lupa like dan komen jam juga
jangan lupa dishare apabila dirasa video
ini bermanfaat apabila masih tetap atas
Saran saya mohon maaf wassalamu'alaikum
