Read the following paragraph and answer the questions.
A digital counter is a set of flipflops whose states change in response to the pulses applied at Input. Counters can be asynchronous counters or synchronous counters. A counter is an example of a state machine; the number of states is called the modulus. Two basic types of state machines are the Moore and the Mealy. In Moore machine, the combinational logic is a gate array with outputs that determine the next state of the flip-flops in the memory. For Mealy machine, the present state affects just as in Moore machine but in addition, the inputs also affect the outputs.
