摘要:
Networks with approximately Gaussian insertion loss characteristics for the shaping and standardization of pulses used in B.B.C. television equipment have previously been designed by Dishal's method based on a Taylor series approximant. A proposal by Jones for an improved Gaussian approximant employing Laguerre polynomials suggested that more effective networks might be possible, Computer programs were written for the realization of the Laguerre approximant networks, and a series of networks was constructed and tested. The Laguerre networks were found to be superior both in their improved shaping and in possessing more convenient element values. Design data for both types are provided in tabular form.
