Q. An interesting application of the SRFF is as a buffer in overcoming contact bounce in mechanical switches. These switches, of the toggle type, may be used to change the logic state in a circuit. However, they suffer from a major problem in that their contacts do not close immediately but continue to make and break for some time after. To avoid such an undesirable state (because it causes the logic state of the circuit to fluctuate), an SRFF is placed between the switch and the circuit, as shown in Figure P6.1.50. Explain the operation as a buffer.
