The decimal equivalent of the largest number that can be stored in a 4-bit binary counter is ________.
Many parallel counters use ________ presetting whereby the counter is preset on the active transition of the same clock signal that is used for counting.
Assume you want to determine the timing diagram for a 4-bit counter using an oscilloscope. The best choice for an oscilloscope trigger signal is ________.
One characteristic of a ring counter is that the modulus is equal to the number of flip-flops in the register and, consequently, there are never any unused or invalid states.
Three cascaded modulus-10 counters have an overall modulus of 1000.
A state diagram is a table of states.
A sequential circuit design is used to ________.
The minimum number of flip-flops that can be used to construct a modulus-5 counter is ________.
A D flip-flop can be made to toggle by ________.
In a full-featured counter in HDL, the concept of rolling over simply means the count sequence has reached its limit and must start over at the beginning of the sequence.
The 7447 has a 4-bit BCD input, seven individual active-LOW outputs, and a ripple blanking input and output.
A reliable method for eliminating decoder spikes is to use strobing.
A ripple counter is an asynchronous counter.
The MOD-10 counter is also referred to as a ________ counter.
The duty cycle of the most significant bit from a 4-bit (0–9) BCD counter is ________.
Assume a 4-bit ripple counter has a failure in the second flip-flop such that it "locks up." The third and fourth stages will ________.
All decade counters are BCD counters.
Shift register counters use logic functions to reset the registers when the desired count is reached.
An asynchronous counter differs from a synchronous counter in the method of clocking.
The MOD number of a Johnson counter will always be equal to one-half the number of flip-flops in the counter.
In general, when using a scope to troubleshoot digital systems the instrument should be triggered by ________.
Shift-register counters use ________, which means that the output of the last FF in the register is connected back to the first FF in some way.
In order to use a shift register as a counter, ________.
The terminal count of a typical modulus-10 binary counter is 1010.
The given circuit is a(n) ________.
A J-K flip-flop excitation table lists the present state, the next state, and the J and K levels required to produce each transition.
