Consider the amplitude-modulated wave of Fig. P7.2 with a periodic triangular envelope. This modulated wave is applied to an envelope detector with zero source resistance and a load resistance of 250 ohms. The carrier frequency, fc = 40 kHz. Suggest a suitable value for the capacitor C so that the distortion (at the envelope detector output) is negligible for frequencies up to and including the eleventh harmonic of the modulating wave. See diagram attached.
