With carrier frequency of 105 Hz. The modulation index is
Question 2
A sinusoidal carrier wave of frequency of fc =100M Hz is exponentially modulated by a modulating signal x(t). find maximum and minimum instantaneous frequency.
if resulting signal is PM with sensitivity kP= 10π Hz/v
Question 3
A carrier frequency modulated with a sinusoidal signal of frequency 4 kHz resulting in a maximum frequency deviation of 7kHz. The bandwidth of modulated signal is
Question 4
13 signals each is band limited to 7 kHz are to be transmitted over a single channel. If AM DSB modulation technique is used and the guard band of 1.5 kHz is present then the bandwidth of the multiplexed signal is ________kHz.
