Fig. 1 shows the series RC high-pass filter circuit. In such circuit, the output is taken across the resistor and practically reactance of the capacitor decrease with increasing frequency.

Consider the series RLC filter circuit shows in Fig. 1(a). If a unit step function is applied, we see that

Simple RC circuits are not used in switching circuits, especially, in integrated circuit. However, inductors are still used, as in the case of current sweep generation, tunnel diode monostable and astable circuits.

Fig. 1 shows the series RC low pass filter circuit. This circuit is identical with that of high-pass filter circuit except for the fact that the output is now taken across
