The Fm signal is applied to the system shown in Figure consisting of a high-pass RC filter and an envelope detector. Assume that

(a) The resistance R is small compared with the reactance of the capacitor C for all significant frequency components of s (t), and

(b) The envelope detector does not load the filter. Determine the resulting signal at the envelope detector output, assuming that k?? | m (t) |

s(t) = A. cos 27ft + 2mk; m(7) dr FM wave Envelope

s(t) = A. cos 27ft + 2mk; m(7) dr FM wave Envelope detector Output R. signal s(1)
