Question

Modulus refers to ____________

(a) A method used to fabricate decade counter units

(b) The modulus of elasticity, or the ability of a circuit to be stretched from one mode to another

(c) An input on a counter that is used to set the counter state, such as UP/DOWN

(d) The maximum number of states in a counter sequence

I had been asked this question in class test.

My enquiry is from Propagation Delay in Ripple Counter in chapter Counters of Digital Circuits

Answer 1

Right option is (d) The maximum number of states in a counter sequence

Easy explanation: Modulus is defined as the maximum number of stages/states a counter has. It is independent of the number of states the counter will actually traverse.
