Counters Questions

• What is the difference between a 7490 and a 7492?
• List the state of each output pin of a 7447 if RBI = 0, LT = 1, A0 = 1, A1 = 0, A2 = 0, and A3 = 1.
• The hexadecimal equivalent of 15,536 is ________.
• Referring to the given figure, at which point is the serial data transferred to the parallel output?
• Three cascaded decade counters will divide the input frequency by ________.
• The terminal count of a 3-bit binary counter in the DOWN mode is ________.
• For a one-shot application, how can HDL code be used to make a circuit respond once to each positive transition on its trigger input?
• One of the major drawbacks to the use of asynchronous counters is:
• When two counters are cascaded, the overall MOD number is equal to the ________ of their individual MOD numbers.
• A 4-bit ripple counter consists of flip-flops, which each have a propagation delay from clock to Q output of 15 ns. For the counter to recycle from 1111 to 0000, it takes a total of ________.
• List which pins need to be connected together on a 7492 to make a MOD-12 counter.

• The circuit given below fails to produce data output. The individual flip-flops are checked with a logic probe and pulser, and each checks OK. What could be causing the problem?
• The process of designing a synchronous counter that will count in a nonbinary manner is primarily based on:

• To operate correctly, starting a ring counter requires:
• What type of register is shown below?
• Which of the following is a type of shift register counter?
• What decimal value is required to produce an output at "X"?
• Select the response that best describes the use of the Master Reset on typical 4-bit binary counters.
