Linear Wave Shaping Aim: i) To design a low pass RC circuit for the given cutoff frequency and obtain its frequency response. ii) To observe the response of the designed low pass RC circuit for the given square waveform for T<<RC,T=RC and T>>RC. To design a high pass RC circuit for the given cutoff frequency and obtain its frequency response. iv) ld iii) To observe the response of the designed high pass RC circuit for the given square Apparatus Required: Name of the Component/Equipment Capacitors CRO Specifications Quantity 1KΩ 1 2.2KΩ,16 KΩ 1 W Resistors or waveform for T<<RC, T=RC and T>>RC. Function generator 1 20MHz 1 1MHz 1 TU Theory: 0.01µF The process whereby the form of a non sinusoidal signal is altered by transmission through a linear network is called “linear wave shaping”. An ideal low pass circuit is one that allows all the input frequencies below a frequency called cutoff frequency fc and attenuates all those above this frequency. For practical low pass circuit (Fig.1) cutoff is set to occur at a frequency where the gain of the circuit falls by 3 dB from its maximum at very JN high frequencies the capacitive reactance is very small, so the output is almost equal to the input and hence the gain is equal to 1. Since circuit attenuates low frequency signals and allows high frequency signals with little or no attenuation, it is called a high pass circuit.
