(a) Why does the δ-pulse appear to be an ideal test signal from a theoretical point of view but not from a practical point of view?

(b) You wish to measure the entire transfer function of a filter according to the absolute value and phase. What do you have to take into account?

(c) Describe a method of measuring the normed transfer function according to absolute value and phase. Select the appropriate circuit from the library of the DASYLab circuits and analyse the method. (d) Complete this process and represent the transfer function as a local curve in the GAUSSian plane.

(e) You are to construct the hardware of a test signal generator. In the case of which signal is this easiest?

(f) What problems are there with the step function as a test signal and how can they be avoided?

(g) How can test signals be generated which have a constant amplitude curve in any specifically defined frequency range?

(h) What advantages and disadvantages do the last mentioned test signals have?

(i) What are the possible fields of application for burst signals as test signals?

(j) What makes the noise signal so interesting as a test signal? And what makes it so difficult?

(k) Measure the correlation factor between two different noise signals and one and the same noise signal. What correlation factors do you anticipate and which do you measure? How does the correlation factor depend on the length of the noise signal? What does the correlation factor represent in terms of content?
