What is synchronous serial input?
synchronous input means that the flipflop reads input only at posedge or negedge of the clock.
Why is a synchronous counter referred to ripple counter?
A synchronous counter is not referred to as a ripple counter. They are two different things. The ripple counter uses the output of each stage to trigger the input of the next stage, resulting in propagation delay between stages. The synchronous counter, on the other hand clocks all stages on the same clock edge, making them all change at relatively the same time.
How does a digital countdown timer works?
a digital countdown timer is simply a digital synchronous counter consisting of registers and flip flops example :to count the number from 0 to 15 we require a four bit synchronous counter which will pass to sixteen stages continuously with shifting from one stage to other after every clock pulse and the cycle continues
What are the disadvantages of asynchronous counter?
Counter circuits made from cascaded J-K flip-flops where each clock input receives its pulses from the output of the previous flip-flop invariably exhibit a ripple effect, where false output counts are generated between some steps of the count sequence. These types of counter circuits are called asynchronous counters, or ripple counters.
What is synchronus and asynchronus sequential circuit in digital electronics?
1.Sync. ckts all f/fs are clocked by single clock. Async. ckts o/p of f/f becomes clk for next f/f. 2. Sync ckts are fast. Async ckts are slow. 3.Sync.ckts are easy to design. Async.ckts are difficult to design.
What is synchronous serial input?
synchronous input means that the flipflop reads input only at posedge or negedge of the clock.
Is I2C synchronous communication?
Yes. It is operating in synchronous with the clock. Two wire communication. SDA, SCL and GND pins.
Difference between synchronous and asynchronous flip flops?
Synchronous flip-flops change outputs synchronously to a clock signal, while asynchronous flip-flops can change outputs regardless of the clock signal. Asynchronous flip-flops are not as commonly used due to potential timing hazards, while synchronous flip-flops are widely used in digital circuits to ensure reliable operation.
Differecne between synchronous circuit and a asynchronous circuit?
Synchronous circuits operate under the influence of s clock pulse while asynchronous circuits operate without the influence of a clock pulse
What is the difference synchronous buses and non synchronous buses?
Synchronous buses use a clock signal to synchronize data transfers between components, ensuring that data is transferred at a predictable rate. Non-synchronous buses transfer data without a clock signal and rely on other mechanisms to coordinate data transmission. Synchronous buses are generally faster and more efficient but can be more complex to design and implement compared to non-synchronous buses.
Which synchronous technique requires the most bandwidth?
Seperate clock signal
Why the synchronous modems are more costly than the asynchronous modems?
Because they contain clock recovery circuits
What is the advantage and disadvantage of a synchronous counter over an asynchronous counter?
1. Easier to design 2. No propagation delay Actually the second one is the most important reason. In designing circuits that work at high clock rates, ripples will result in errors so synchronization is very very important.
What are synchronous input for j-k flipflop?
JK flip flop are synchronous ONLY when the rise or the fall edge of the clock will transfer the data to the outputs
What are synchronous input for j k flipflop?
JK flip flop are synchronous ONLY when the rise or the fall edge of the clock will transfer the data to the outputs
How accurate is the most accurate clock on earth?
The most accurate clock is an atomic clock invented at the university of Colorado in the United States.The atomic clock is accurate to within 1 second in 200 million years.
Practical example of where SRAM used for?
The "S" stands for Synchronous RAM. By Synchronous that means it worked with the system clock and the speed of the RAM is the same as the speed of the system bus. So if the system bus is operating at 100MHz then Synchronous RAM also operated at 100MHz. It has since been replaced by Double Data Rate RAM (DDR). Double Data Rate goes twice as fast as the system clock, it sends data on the upswing of the clock and again on the downcycle of the system clock so it can send data twice as fast as the Synchronous RAM which sent data once per clock cycle. Hope this helps.
