Question
(i)
(ii)
Draw a half-wave rectifier circuit with a diode which produces a
negative output voltage waveform from the following input AC
waveform: Vin = 10 sin(10nt) V.
In a voltage versus time graph sketch the input and output
voltages waveforms. You should show at least 2 periods of the
input and output voltage signals, the peak values of the input and
output signals and the period of these signals in seconds. Consider
that the diode's cut-in voltage (starts to conduct), V is 0.7 V.

Consider that the diode's cut-in voltage (starts to conduct), V is 0.7 V.
(iii) A capacitor is used for smoothing the output voltage waveform in
a half-wave rectifier circuit. Indicate where this capacitor is placed
in the circuit and calculate its value if the ripple voltage, Vr, is to
be limited to 0.1 V. The input AC waveform is Vin = 10 sin(10nt) V,
the value of the load resistor is 400 kn and you can assume that
the diode is ideal, i.e. has negligible resistance and its cut-in
voltage, V, is 0 V.
