(a) Explain the general difference between an analog and digital signal in the time domain
(b) What graphic possibilities does DASYLab provide for digital signals (see Illustration 188 and Illustration 189)?
(c) Digital signals can only be analyzed in segments. What problems result from this?
(d) Explain the influence of the two quantities block length n and sampling rate fS on the representation of a digital signal in the time domain. How should these quantities be selected so that the digital signal on the screen is as similar as possible to the analog input signal?
(e) Explain the term "digital period length TD"
(f) When is the spectrum of a periodic analog signal reproduced correctly via digital signal processing by means of FFT?
