Q3)
Two 555 timers are connected together as shown in Figure Q3. Thediode in the figure is an ideal diode
(a) Draw and completely label the waveforms for V01, VC1, V0 andVC3. All the waveforms must be drawn parallel at the time-axis.Clearly show the relationship between these waveforms. (8marks)
(b) Calculate the duty cycle of the output waveform V0. (8marks)
