The impulse response of this circuit is h(t) = A ( 2Ts 12 where Ts is the sampling interval. Consider a typical sampled signal ğ(t) and show that this circuit performs the linear interpolation. In other words, the filter output consists of sample tops connected by straight-line segments. Follow the procedure discussed in Sec. 5.1.2 (Fig. 5.6) for a typical signal g(t).

- 9-3) similar to Lathi & Ding, Prob. P.5.2-3 In a satellite radio system, 200 stereo stations are to be packaged in one data stream. For each station, two (left & right) signals of bandwidth 22 kHz are sampled, quantized, and binary-coded into PCM signals. The transmitter then multiplexes the data from the 200 stations into a single stream via TDM and modulates that stream onto a radio carrier using DSB-SC-AM. (a) If the maximum acceptable quantization error is 0.25% of the peak signal voltage, find the minimum number of bits needed for a uniform quantizer. (b) If the sampling rate must be 25% higher than the Nyquist rate, find the minimum bit rate of the multiplexed data stream, based on the quantizer of part (a). (c) If 10% more bits are added for error correction and framing, determine the minimum bandwidth of the radio signal sent to the ground receivers.arrow_forward9-2) similar to Lathi & Ding, Prob.

(c) Determine the number of binary digits per second (bit/s) required to encode the audio signal.
