Abstract
The invention relates to an electrical filter circuit operated with a definite sampling and clock frequency f.sub.T, such filter being made up of CTD elements, and having at least one bipolar or quadripolar resonator in the form of a self-contained conductor loop (for example, C.sub.1, C.sub.2) with unidirectional transmission behavior. Differences in the transfer capacitances of such circuits are reduced, as far as possible, in order to thereby simplify integrated manufacture as far as possible, by positioning the frequency band to be filtered out at a frequency position which lies above half the clock frequency (f.sub.T /2), or in the range from f.sub.T /2 through 3f.sub.T /2.
