The circuit shown below is a ________.
Dependency notation is no longer used.
The concept of a counter to implement a digital one-shot using HDL is not used.
A parallel in/serial out shift register enters all data bits simultaneously and transfers them out one bit at a time.
The modulus of a counter is the actual number of states in its sequence.
To design a divide-by-200 counter using synchronous counters, two 4-bit counters could be cascaded together to form an 8-bit counter.
To cascade is to connect in parallel.
Generally speaking, the synchronous counter requires more circuitry than an asynchronous counter.
All flip-flops in an asynchronous counter change states at the same time.
When a J-K flip-flop is used in a circuit, we only have to consider the level at J and K at the active clock edge to know the states of the outputs.
Cascade means to connect the Q output of one flip-flop to the clock input of the next.
Another term used to describe up/down counters is bidirectional.
When implementing a complete system application using IC counter chips, output devices such as LED indicators must be configured to operate from the counter outputs.
A glitch is a short pulse resulting in an undesired result in a digital circuit.
Asynchronous counters are known as modulus counters.
In a synchronous counter, each state is clocked by the same pulse.
Basic counters can be cascaded in parallel to increase the number of data bits that the counter can handle.
In a 74192 BCD decade up-/down-counter, the terminal count up and the terminal count down are active-LOW.
An effective time delay device can be constructed by using the propagation delay characteristic of parallel shift registers.
In VHDL, when we want to remember a value it must be stored in a VARIABLE.
Counters are generally decoded in order to determine their count state.
The term synchronous refers to events that do not occur at the same time.
Synchronous binary counters can only be used for the application of timing of digital systems.
In a seven-segment LED display, the BCD must be decoded into a format that can be used to drive the decimal numeric display.
Parallel in/parallel out registers have parallel input and output busses.
Phototransistors have varying resistance from collector to emitter, depending on how much light strikes them.
Most sequential circuits contain a combinational logic section and a memory section.
The term synchronous, as applied to counter operations, means that the counter is clocked such that each flip-flop in the counter is triggered at the same time.
Once an up/down counter begins its count sequence, it cannot be reversed.
Shift registers are used to store and transfer data.
