A three-stage type D counter circuit is required to produce the waveforms below.
A skeletal form of the counter circuit is given in the PSpice schematic* of FIGURE 1 below, along with the associated truth table. The outputs of the circuit are A, B and C and they are generated by the counter outputs Q1, Q2 and Q3.
a) Derive the relationship [a Boolean expression] between each output and the inputs [by, for example, plotting a Karnaugh map for each output].
b) Complete the PSpice circuit.
c) 'Run' the circuit to generate the required waveforms.
