Question

In an AM radio receiver the received signal is given as X1(t)

m(t)cos(2π10000t) where m(t) represents the message signal. We want to

translate the received signal to X2(t) = m(t)cos(2π5000t). Explain how can we

perform the above task.[You have to show the block diagram]

Answer 1

We need to change the frequency of the signal to obtain the required frequency at the receiver.
