Demonstration scheme for impulse response of various systems

In linear system theory impulse response of any system is of great significance. It is the impulse response which is helpful in determining the convolution in continuous time system (unit sample response in Digital Signal Processing). The impulse response of simple systems can be calculated from the system differential equation or from the transfer function of the system (by taking the inverse Fourier Transform of transfer function). To the best of author’s knowledge there exists no such scheme in the literature so far showing any practical method that can demonstrate the impulse response of a system on the oscilloscope. In this paper the method of demonstrating the impulse response of any linear system to the undergraduate students is presented. The approach is simple and is developed with minimum component count.
