Abstract :
The Fourier method for time domain synthesis is applied to find the transfer functions of five-, seven-, and nine-pole networks that have an impulse response approximating a sine-squared pulse to an increasing degree of accuracy. Results are compared to a seven-pole Thomson network. Where the departures of the impulse response from the sine-squared curve reach 2 percent of the peak amplitude in a seven-pole Thomson network, the new seven-pole network does not exceed 1.3 percent, whereas the nine-pole network is within 0.7 percent. Practical networks are synthesized from the transfer functions, both of the single-and double-terminated ated type.
