10.9. For the system of P10.3, the input signal is x[n], the output signal is y[n], and the im- pulse response is h[n]. For each of the following cases, find the output y[n]: (a) x[n] = au[n], h[n] = bu[2-n] (where a + b). (b) x[n] = a"u[−n], h[n] = b"u[n] (where a + b). (c) x[n] = u[n]. h[n] = a"(u[n] - u[n-100]). (d) x[n] = u[-2-n]. h[n] = bu[n-1] (where |b| > 1). (e) x[n] = au[n], h[n] = b"u[n-2]. (where a² + b). - (f) x[n] = u[1n], h[n] = (u[n] - u[n-51]).

A sinusoid signal v(n) = 5 sin( @₂ .n) with f=5 Hz and fs = 10 kHz has to be quantized @ (Vq(n) = Q[v(n)]) with a midtreat quantizer. The range of the signal is ±5 V and the word length of the quantizer 4 bits. The quantizer is at digital full scale. (a) How many quantization levels L does the quantizer have? What is the value of A? (b) Sketch the input-output characteristic of the quantizer. How different is a midtreat quantizer to a midrise quantizer. (c) For time index n = 1250 calculate the quantized value v₁ (n), the quantization error eq(n) and represent vą (n) using RZ code. (d) Calculate the power P of the quantization noise. (e) Determine the SNR in dB.

What is SNRQ, rounded to the nearest dB, that a 10-bit uniform quantizer is expected to have for a full-scale sinusoidal input signal? (a) 50 dB (b) 62 dB (c) 74 dB (d) 98 dB O (a) O (b) O (C) O (d) A Moving to the next question prevents changes to this answer. Type here to search hp %2:

Refer to the system shown in figure below Ideal Sampler LTI Assume that, h(t) = 4 sinc(4 t) and the spectrum of the input signal x(t) is as shown in the figure below S(HZ) a. Assume fs = 7 HZ, plot the spectrum of the sampled signal z(t), (show the important points) and find the output signal y(t). b. Assume fs = 3 HZ, plot the spectrum of the sampled signal z(t), (show the important points).
