Test: Ring Counters - Electronics and Communication Engineering (ECE) MCQ

A transceiver is a device comprising both a transmitter and a receiver which are combined and share common circuitry or a single housing. When no circuitry is common between transmit and receive functions, the device is a transmitter-receiver.

There is no such type of register present who doesn’t have output end. Thus, Serial in/Parallel in is not a characteristic of a shift register. There has to be an output, be it serial or parallel.

The function of a buffer circuit is to provide an output that is equal to its input. A transceiver circuit is a buffer that can operate in both directions right as well as left.

74HC195 is an IC, which can be used for all of the given operations, as well as for, parallel-in/parallel-out.

In shift-right register, shifting of bit takes place towards the right and towards left for shift-left register. Thus, both the registers vary in the shifting of their direction.

In computer or memory technology, a strobe is a signal that is sent that validates data or other signals on adjacent parallel lines. Thus, in registers the strobe line is there to check the availability of data.

A ring shift counter is a counter in which the output of one FF connected to the input of the adjacent FF. In preset condition, all of the bits are 0 except first one.

UART means Universal Asynchronous Receiver/Transmitter which converts the bytes it receives from the computer along parallel circuits into a single serial bit stream for outbound transmission. And also receives data in serial form and converts it into parallel form and sent to the processor.

A transceiver circuit is a buffer that can operate in both directions right as well as left.

Synchronous counters are the counters being triggered in the presence of a clock pulse. Since all of the clock inputs are connected through a single clock pulse in ring shift and johnson counters. So, both are synchronous counters.
