SR Flip Flop
The SR flip flop is an arrangement of logic gates that maintain astable output even after the input are turned off. It has two inputs namely SET input (S) and RESET input ( R) and two outputs Q and Q. In a SR flip flop activating the SET input will switch it to the other state. Classical SR flip flop requires two NAND gates or two NOR gates. The block diagram of SR flip flop is shown in the outputs of a basic SR flip flop SR flip flop change whenever its R or S change appropriately. The SR flip flop can be implemented by using NOR or NAND gates as follows.
Find the maximum frequency of an output sine wave which can be produced at an amplitude of 1.5 V if the op-amp slew rate is 0.5 V/µs.
