The duty factor of the pulse
generator in the diagram is variable
in 10% steps from 10% to
90%.
With the aid of thumb wheel
switch S1, a 4-bit word, S, is
added to one input of IC1 and
to IC2. Circuit IC1 is a full
adder, while IC2 functions as a
switch. The binary equivalent of
5 is applied to the other input of
IC1. The output of IC1 is linked
to the second input of IC2.
