Demodulation is the process of extracting the message signal from the modulated signal. The demodulation process depends on the type of modulation employed. For DSB-AM and SSB-AM, the demodulation method is coherent demodulation, which requires the existence of a signal with the same frequency and...

Therefore, Equation 3 and Equation 8 are the two formulas for Modulation index. The modulation index or modulation depth is often denoted in percentage called as Percentage of Modulation. We will get the percentage of modulation, just by multiplying the modulation index value with 100....
Pulse-Width Modulation (PWM) adjusts the width of the pulse based on the input signal, while Pulse-Position Modulation (PPM) changes the position of the pulse based on the input signal. PAM is simple but susceptible to noise, PWM is efficient and used in digital communication, and PPM is...
MATLAB Online에서 열기 Here's one way to do this. I'm showing two graphs, one with 5 Hz amplitude modulation, one with 5 kHz amplitude modulation. I've also passed the modulated signal into the sound function, so you can hear the result as well. At ...
