Q.How Amplitude modulation achieved?
B. THE FREQUENCIES OF TWOSIDE BANDS IN AN AM WAVE ARE 640KHZ AND 660KHZ RESPECTIVELY.FIND THE FREQUENCIES OF CARRIER AND MODULATING SIGNAL.WHAT IS THE BANDWIDTH REQUIRED FOR AMPITUDE MODULATION?
At the transmitter end the low frequency modulating signals are superimposed on high-frequency carrier wave
at the receivers end the information which is received will change in amplitude according to the biasing voltage
