1.	Am Wave May Be Represented As E(t) Cos ωct Where E(t) Is
Answer» An AM wave may be represented by s(t) = [A+ x(t)] COS ωct = E(t) cos ωct Where x(t) is the MODULATING signal A is the amplitude of CARRIER wave E(t) is the Envelope of the AM wave The envelope consists of the modulating signal that may be recovered from AM signal USING demodulation techniques. An AM wave may be represented by s(t) = [A+ x(t)] cos ωct = E(t) cos ωct Where x(t) is the modulating signal A is the amplitude of carrier wave E(t) is the Envelope of the AM wave The envelope consists of the modulating signal that may be recovered from AM signal using demodulation techniques.

Answer»

An AM wave may be represented by

s(t) = [A+ x(t)] COS ωct
= E(t) cos ωct

Where x(t) is the MODULATING signal

A is the amplitude of CARRIER wave

E(t) is the Envelope of the AM wave

The envelope consists of the modulating signal that may be recovered from AM signal USING demodulation techniques.
