1. A two-port network is free of linear distortion in the frequency range fMIN to fMAX if it meets which pair of criteria?

The correct answer is e, constant group delay and constant magnitude of the transmission coefficient.

2. The graph below shows the phase and magnitude of which type of filter?

The correct answer is b, bandpass.

3. Impulse functions are often used to characterise networks because of their wide frequency content. An impulse function is also known as:

The correct answer is d, Dirac Function.

4. VNAs generate sinusoidal signals as a stimulus for the network under test. Which kind of circuit is used to ensure the signal's frequency stability and spectral purity?

The correct answer is a, phase-locked loop.

5. The plot below is an example of:

The correct answer is c, group delay.
