What Is the Counters and Shift Registers Board Used For?
Counters and shift registers are the sequential circuits behind clocks, timers, frequency meters and the data paths of computers, and this board lets students build them stage by stage rather than only read about them. A counter is a chain of flip-flops that changes state on each clock pulse, and a shift register moves its stored bits one place along the chain on every pulse, which is how serial data is turned into parallel data and back again. Students connect the flip-flops and gates on the programmable panel into the counter or register they are studying, clock it, and follow the count on the decoder and seven-segment display.
The application experiments link these circuits to real systems: frequency measurement and frequency division with counters, and the basic storage cell that shows the principle of random access memory. Together they make the board a broad digital electronics trainer kit for the sequential-logic part of a digital electronics course.
What to Specify When Ordering
- Board — this counters and shift registers board for the sequential-logic practicals.
- Quantity — the number of boards for your digital electronics lab.
- Companion boards — the gate, flip-flop, encoder and decoder trainers listed below are separate boards that can be quoted on the same enquiry.
Frequently Asked Questions
What is the difference between a ripple counter and a synchronous counter?
In a ripple counter each flip-flop is clocked by the output of the one before, so the change ripples down the chain and the outputs settle one after another. In a synchronous counter every flip-flop shares the same clock and the outputs change together; the parallel-carry and series-carry versions on this board show two ways of generating the carry between stages.
What is a Johnson counter?
A Johnson, or twisted-ring, counter is a shift register whose inverted last output is fed back to the first stage. With n stages it runs through 2n states, which is why a 5-stage shift counter gives the decade counter on this board.
What is a 2421 BCD counter?
It counts in the 2421 code, a weighted binary-coded decimal code whose bit weights are 2, 4, 2 and 1. The code is self-complementing: inverting every bit of a digit gives its nines’ complement, which simplifies decimal subtraction.
How does the board show frequency measurement and frequency division?
A built-in 4-bit binary counter demonstrates the basic principle of frequency measurement: the number of pulses counted in a known time gives the frequency. For frequency division, the square wave oscillator, with 10 Hz, 1 kHz and 10 kHz ranges and coarse and fine variation, drives a counter whose output runs at a fraction of the input frequency set by its modulus.
What information is needed for an export quotation?
Tell JLab the number of boards, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling instructions, and the tender reference if one applies.
Who manufactures this training board?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and supplies it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of electronics trainers and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The counters and shift registers board is produced at JLab’s own works, not bought from a trader, so institutions, dealers and importers order straight from the manufacturer, each board is visually inspected before dispatch, and repeat orders and service parts stay with the same company. JLab exports worldwide and ships to buyers in every region — for example Moldova in Eastern Europe, Yemen in the Middle East, Senegal in West Africa, Australia in Oceania and Lesotho in Southern Africa. For tender purchases, see the JLab lab tenders page.
