Advantages / Disadvantages of Synchronous CountersĪ digital binary counter is a device used for counting binary numbers.The symbol for negative or falling edge sensitive T flip-flop is given below. The symbol for positive or rising edge sensitive T flip-flop is given below: Sum Of Product (SOP) & Product Of Sum (POS).The schematic of T flip-flop is given below: Comparator and Digital Magnitude Comparator.T flip-flop characteristic table is given below: The characteristic table shows the short form of the truth table. When T = 0, the flip-flop hold its state Q = Q. When T = 1, the output keeps changing Q = Q̅ upon each clock cycle. JK inputs of JK flip-flop combine together to form a single input T. T flip-flop is modified version of JK flip-flop. JK flip-flop eliminates the problem of restricted input of SR flip-flop. The symbol for negative or falling edge sensitive JK flip-flop is given below. The symbol for positive or rising edge sensitive JK flip-flop is given below:

DEMUX – Demultiplexer | Types, Construction & Applications.MUX – Digital Multiplexer | Types, Construction & Applications.Its schematic is given in the figure below. SET and RESET should not be “High” when the clock is triggered as it is considers as invalid input condition which leads to unpredictable output result. If the input RESET is High when the clock is triggered, the Output “Q” would be “LOW”. The Output “Q” is High if the input as SET is High (when the clock is triggered). It has two inputs known as SET and RESET. SR Flip-flop is the most basic sequential logic circuit also known as SR latch. You may also read: Ripple Carry And Carry Look Ahead Adder.Most common types of flip-flops are as follow. Difference Between Flip-Flops & Latchesīelow are some common differences between Flip-flops and latches. That control signal is known as a clock signal Q. It means that the latch’s output change with a change in input levels and the flip-flop’s output only change when there is an edge of controlling signal. Latches are level sensitive and Flip-flops are edge sensitive. Symbol and Circuit of Basic SR Flip-Flopĭigital flip-flops are memory devices used for storing binary data in sequential logic circuits.Difference Between Flip-Flops & Latches.
