Comprehension:
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.
Q. Which of the following statements is correct about counter?
  • a)
    Design and implementation of asynchronous counter becomes tedious and complex as number of states increases
  • b)
    The main drawback of Asynchronous counters is their low speed as clock is propagated through a number of flip-flops
  • c)
    Synchronous counter flip-flops can never be clocked simultaneously
  • d)
    A counter in which the maximum number of states can be changed is called full modulus counter
Correct answer is option 'A'. Can you explain this answer?

Comprehension:Read the following paragraph and answer the questions.A ...
  • Design and implementation of asynchronous counter becomes tedious and complex as number of states increases.  Asynchronous counters are prone to race conditions and glitches which can lead to errors in the outputs.
  • As the number of states increases, the complexity of the counter design increases and the chances for errors also increases.
  • As the number of states increases, the design and implementation of asynchronous counters become more complex and tedious. This is because the circuitry required to implement an asynchronous counter needs to be designed in such a way as to ensure that the state transitions only occur in the correct order.
  • This requires careful consideration of the logic and design of the counter and also the timing of the signals being used to control the state transitions. As the number of states increases, the complexity of this process increases.
  •  Asynchronous counters are more complex to design and debug than synchronous counters, as the timing of each stage of the counter must be taken into account.
  • Asynchronous counters also require more logic elements than synchronous counters, making them more expensive and less efficient.
  • Asynchronous counters are also prone to glitches, in which the output changes momentarily due to the asynchronous nature of the counter.
  • Synchronous counters are digital circuits that count in a particular sequence based on the clock signal applied to them. They have a series of flip-flops connected in a chain, and the output of each flip-flop is connected to the clock input of the next flip-flop in the chain.
  • When the clock signal is applied, the first flip-flop toggles its output, which then triggers the next flip-flop to toggle its output. This process continues until the last flip-flop in the chain toggles its output. The output of each flip-flop in the chain is combined to form the count value, which can be used to represent the number of clock pulses that have passed.
  • A full modulus counter is a type of counter in which the maximum number of states can be changed. It is a digital circuit that counts from 0 to a maximum count value, then resets to 0 and continues the cycle.
