Factors Affecting the Measured Value of Impulse Bandwidth

The errors introduced in the measured value of impulse bandwidth obtained by determining the area under the response curve are discussed. The required pulse width of a narrow pulse used to stimulate the impulse response of a linear network is also analyzed. The results are presented in terms of the integral-square error between the true impulse response and simulated response as a function of band-width-pulse-width product. The trapezoidal method of numerical integration as applied to this measurement is briefly discussed.
