What is synchronous serial input?
synchronous input means that the flipflop reads input only at posedge or negedge of the clock.
Difference between synchronous generator and synchronous motor?
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
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.
Difference between synchronous and asynchronous flip flops?
synchronous means it is based on a clock...it performs operations based on every clock tick....asynchronous operations execute irregardless of the clock signal
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.
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
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 difference synchronous buses and non synchronous buses?
Synchronous buses are clocked, and things happen only at the clock Ticks while in asynchronous buses a certain protocol must be used to enforce timing.
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
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.
First DIMM to run synchronized with the system clock?
SDRAM runs synchronized with the system clock
Difference between synchronous bus and asynchronous bus?
1. Syncrhonous bus includes clock in control lines whereas asynchronous bus is not clocked. 2. the devices which need to be connected by synchronous bus should be at same speed whereas an asynchronous bus may connect many devices with varying speeds. 3. A fixed protocol is defined to communicate using synchronous bus which is relative to the clock. An asynchronous bus uses handshaking protocol.
