Refer to the IC counter circuit in Figure 7-107(b):

(a) Describe the counter’s output on QD QC QB QA if S̅T̅A̅R̅T̅ is LOW.

(b) Describe the counter’s output on QD QC QB QA if S̅T̅A̅R̅T̅ is momentarily pulsed LOW and then returns to a HIGH.

(c) What is the counter’s modulus? Is this a recycling counter?
