What is programmable counter in digital electronics?
(electronics) A counter that divides an input frequency by a number which can be programmed into decades of synchronous down counters; these decades, with additional decoding and control logic, give the equivalent of a divide-by-N counter system, where N can be made equal to any number.
Which is are the applications of programmable counter?
These programmable counters are used in manufacturing and process applications to control batch lot size, material cut-lengths, punching or drilling, stacking, and many other count, position, or length related operations.
How does a digital counter work?
Counter is a digital device and the output of the counter includes a predefined state based on the clock pulse applications. In synchronous counter, only one clock i/p is given to all flip-flops, whereas in asynchronous counter, the o/p of the flip flop is the clock signal from the nearby one.
What are different types of counters?
Types of Counters
- Asynchronous Counters.
- Synchronous Counters.
- Asynchronous Decade Counters.
- Synchronous Decade Counters.
- Asynchronous Up-Down Counters.
- Synchronous Up-Down Counters.
What is meant by programmable counter?
A programmable counter/timer is a flexible microprocessor. peripheral that counts the edges (voltage transitions) that occur. on an input signal.
What is meant by programmable counter mention its application?
What is meant by programmable counter? Mention its application. · A counter that divides an input frequency by a number which can be programmed into decades of synchronous down counters.
What is the purpose of a digital counter?
Counters are used in digital electronics for counting purposes, they can count specific events happening in the circuit. For example, in the UP counter a counter increases the count for every rising edge of the clock.
What is counter and its application?
Counters are used not only for counting but also for measuring frequency and time ; increment memory addresses . Counters are well known to us as “Timers”. Counter circuits are the best example for the flip flop applications. Counters are designed by grouping of flip flops and applying a single clock signal to them.
How are presets used in a programmable counter?
A variety of programmable or presettable counters is available. By presetting the stages of a counter, one can achieve timing because the counter can be made to reset or “fill up” when the preset count has been reached. Another application is to divide the input frequency by a preset or programmed number.
What does a counter do in digital logic?
Counters in Digital Logic. According to Wikipedia, in digital logic and computing, a Counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock signal.
Where can I find an up down counter?
This IC is also found in analog to digital and digital to analog converter systems and in computers to generate magnitudes and polarity signs. Up Down counter are available with programmable inputs, with divide by N features, and with other capability. Loading…
What are the different types of counter IC?
In this article we will discuss about two different counter IC, Programmable and Up Down Counter IC. Programmable divide by N counter IC (F4526) and UP Down counter (SN74192). We will discuss about key parameter and applications.
