1. The following diagram shows a periodic voltage.

(i) What is meant by "periodic'?
(ii) Is this an altemating or a unidirectional voltage?
(iii) What is the magnitude of the DC component?
(iv) What is the peak-to-peak value of the AC component?
(v) Determine the frequency of the waveform.
2. What is a rectifier? Why may a diode be used as a rectifier?
