An FM signal with modulation index β = 1 is transmitted an An FM signal with modulation index β = 1 is transmitted an ideal band-pass filter with mid-band frequency A?c and bandwidth 5A?m, where A?c is the carrier frequency and A?m is the frequency of the sinusoidal modulating wave. Determine the magnitude spectrum of […]

An Fm signal with a frequency deviation of 10 kHz An Fm signal with a frequency deviation of 10 kHz at a modulation frequency of 5 kHz is applied to two frequency multiplier connected is cascade. The first multiplier doubles the frequency and the second multiplier triples the frequency. Determine the frequency deviation and the […]

Consider Equation (4.108), which defines the impulse response of Figure shows the cascade connection of a linear channel and a synchronous tapped delay-line equalizer. The impulse response of the channel is denoted by c (t), and that of the equalizer is denoted by h (t). The h (t) is defined by, where T is the […]
