数字信号处理基础(Joyce Van de Vegte) 英文版课后答案（第一章）

Chapter 1 Solutions

1.1 Analog: Defined at every point in time, and at all possible amplitudes.

Digital: Defined only at certain points in time, and only at certain

amplitudes.

1.2

 less dependent on component tolerances

 less affected by noise

 more predictable behavior

(c) temperature

(d) light

(e) acceleration

(f) light

(g) temperature

1.4 During the acquisition time of the sampler, the output of the sample and hold

circuit follows the input signal. For the remainder of the cycle, the output remains steady.

The acquisition time accounts for 1/20 of each sampling period.

1.5 Each sample period is 1/11.025 kHz = 90.7 sec. The acquisition time is 10 sec,

which leaves 80.7 sec for quantization and digitization.
