Amplitude modulation is the process in which instantaneous amplitude of audio frequency is directly proportional to the amplitude of the high frequency carrier wave. Formula used to calculate the depth of modulation is M=Vm / Vc = Vmax - Vmin / Vmax + Vmin The ...

Modulation is a process in which the audio signal having very low frequency is put on a sine wave having frequency higher than that of the audio signal. The equation which represents the sine wave is given below: In the above equation E represents the maximum voltage ...

Communicate means to exchange information between each other. There are lots of ways available through which we can communicate with each other. These are speech, gestures etc. Basically long distance communications are done with the help of electrical signals. Electrical signals can reach to longer distances ...
