Synchronous logic is a type of digital logic circuit where the operation of the circuit is coordinated by a clock signal. All changes in the state of the circuit occur in sync with the clock's rising or falling edges, ensuring that data transitions happen at predictable times. This approach simplifies the design and analysis of circuits, as it allows for easier timing management and reduces the risk of race conditions. Common applications include flip-flops, registers, and synchronous state machines.
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
A MOD-32 synchronous up/down counter can be designed using five flip-flops (since 2^5 = 32) and additional logic for the up and down counting operations. The counter increments or decrements its state based on a control input (up/down signal). The clock input synchronizes all flip-flops, ensuring they change state simultaneously. Logic gates are used to determine the next state based on the current state and the control input, effectively allowing the counter to count from 0 to 31 in both directions.
To design a decade synchronous counter, you start by using flip-flops, typically JK or D flip-flops, to create a 4-bit binary counter that can count from 0 to 9 (ten states). The counter increments on each clock pulse, and you implement combinational logic to reset the counter when it reaches the state representing 10 (1010 in binary). This reset logic can be achieved using AND gates to detect the 10 state and feed back to the reset inputs of the flip-flops. Finally, ensure that the clock input is connected to all flip-flops to maintain synchronization.
synchronous input means that the flipflop reads input only at posedge or negedge of the clock.
Slip, , is defined as the difference between synchronous speed and operating speed, at the same frequency, expressed in rpm or in percent or ratio of synchronous speed. Thus
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.
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
The meaning of synchronous in Tamil is "ஒருவரின் நடப்பு அல்லது இறுதிவார்த்தைக்கு பின்பற்றுவது."
A synchronous motor runs at synchronous speed, so there is no slip, or zero slip.

The synchronous children were all born in 1999.
synchronous generator
Synchronous: The synchronous format, receiver or transmitters are synchronized. A block of information is transmitted along with the synchronization information. This is clk oriented transmission format. This information is specially used for high speed transmission. Usually in this synchronous system one or two SYNC character are used for data synchronous data system. Transmission device send data continuously to receiving device. If the data is not ready this system continuously synchronous data until the data is unviable. Asynchronous: It is character oriented. Each character comes with the information of start and stop. In this system 1 for mark, 0 for space. When data are being transmitted a receiver stay at high at logic 1. This is specially used in low speed transmission.
