Abstract:

A commutative filter is a bandpass filter capable of very high Qs, large range of resonant frequency 0 to 2 megahertz that can be electronically tuned, comb-filter frequency response, small bandwidth independent of resonant frequency, and extremely small size can be constructed of integrated circuits since no inductors are required. The purpose is to present the general theory and evaluation of a commutative filter, in which presentation the effects of leaky capacitors and load resistance are considered. An eight-channel filter is built, and laboratory and theoretical results are compared for the transfer function, bandwidth, quality factor, and sensitivity of the commutative filter. The commutative filter is also investigated from the viewpoint of enhancement of signal-to-noise ratio.
