A. 111 629 Tested in this manner over a range of 50 to 10,000 cycles, the single-stage amplifier..has been shown to have a net amplification over this range equal to that at zero frequency, with an entire absence of measurable phase distortion. 1961 G. Millerson Technique Television Production iii. 43 Certain video distortions, from phase-distortion to signal reflections, can also be the reason for poor definition in a picture. 2000 Proc. National Acad. Sci. U.S.A. 97 14749/2 This procedure is equivalent to filtering in the frequency domain, which is an acausal and symmetric filter that causes least filtering artifacts such as phase distortion. < as lemmas |
