The modulated signal y(t)=m(t)cos(400pit). Calculate the carrier frequency of the given signal

The impulse response of a system is h(t)=(t-2)u(t). For an input u(t-1), the output is

The impulse response of a system is h(t)=t²u(t). For an input u(t-1), the output is

A signal is sampled 2khz and is quantized using 8-bit uniform quantizer assuming SNR for a sinusoidal signal, the bit rate is

Four messages are band limited to w,w,2w and 2w are to be multiplexed using time division multiplexing. The minimum bandwidth required for transmission is

A band limited signal with a maximum frequency of 4khz is to be sampled. According to the sampling theorem, the sampling frequency which is not valid is

Three analog signals,having bandwidths 600hz,600hz and 300hz are sampled at their respective Nyquist rates, encoded with 12 bit words and time division multiplexed. The bit rate for the multiplexed signal is
