Classification and Types of Analog ... Amplitude modulation is a type of analog modulation in which the amplitude of the high frequency carrier signal is changing with respect to the instantaneous amplitude of the modulating signal. In amplitude modulation, the amplitude of the carrier signal changes instantaneously with respect to the amplitude of the modulating signal. Radio Electronics: Amplitude Modulator (AM) dummies Electronics All in One For Dummies. This circuit uses a 1 MHz crystal oscillator, which is often used to generate the clock frequencies for microprocessor circuits. 1 MHz is perfect for a simple AM transmitter circuit because 1 MHz falls right in the middle of the band that’s used for AM radio transmissions. The need of Modulation in munication System Detection is the process of recovering the modulating signal from the modulated carrier wave. In order to obtain the original message signal m(t ) of angular frequency Ém, a simple method is shown in the form of a block diagram.
