A Synchronous Sequential Circuit is a system whose behavior can be defined on the timing of their signals , where in the case of asynchronous sequential circuit depend upon the order in which its inputs signals change and can be affected at any instance of time .

What is synchronous impedance?
Synchronous impedance is also known as the EMF method. It is a ratio of open circuits to short circuits, when they both are referred to the same field excitation.
Application and uses of sequential logic circuits?
Read about logic ring counters.
Where do usually series circuit used?
Series circuits are used in areas where the operation of the circuit is required to be linear.
What is an Induction Machine?
An asynchronous alternating-current machine, such as an induction motor or induction generator, in which the windings of two electric circuits rotate with respect to each other and power is transferred from one circuit to the other by electromagnetic induction.Reference: Wiki Answers
Why star connection used in transmission?
Transmission circuits are prone to earth faults.Only star connection permits flow of earth fault current and the operation of earth fault relays.
Why the synchronous modems are more costly than the asynchronous modems?
Because they contain clock recovery circuits
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 clocked-mode sequential circuit?
A sequential circuit is a type of logic circuit. It sends an output that is dependent upon the present input in addition to the history of the input. That makes it different from a combinational circuit, whose output depends solely on the present input. Given their reliance on input history (or stored input), sequential circuits are particularly useful in computer random access memory (RAM). The two types of sequential circuits are synchronous circuits and asynchronous circuits.
What is the advantage of syncronous circuits over asynchronous circuits?
faster operation
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.
What has the author L L Kinney written?
L. L. Kinney has written: 'Decomposition of asynchronous sequential switching 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.
How synchronous work?
With timing, sent from end to end. Examples are synchronous data with explicit timing circuits at interfaces and plesiochronous where the timing is embedded in the main signal by line codes. Asynchronous, without timing is historical and relates to teleprinter speeds up to 300 bit/s.

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 the advantage of asynchronous circuits over synchronous circuits?
mainly power consumption decreases in asynchronous chips they works based on time(i.e., when its term comes) but programming is of asynchronous chips are more difficult task because of we have to switch ON the chips one by one for that we have to determine the exact time that a single chip takes to complete its given instruction after completion we have to switch on the another chip. while in the sych..chips single clock circulates entire system and all the chips should be in working state
What are sequential circuits and what is a race around condition in sequential circuits?
A circuit is a plan of exercises one does to get fit and a sequential circuit is a set of these one does one after the other, it is called circuit training.
