Abstract
In one exemplary embodiment errors due to tape flutter are overcome by recording along with the analog signal clock pulses having a rate sufficient for sampling of the highest frequency component of the analog signal. Then on playback, the reproduced clock pulses control sampling and storage of samples of the reproduced analog signal. By reading out the samples from storage at a uniform clock rate, the effect of flutter on the reproduced signal is eliminated. In another example the recorded clock rate overcomes tape skew and other mechanical irregularities in recording and reproducing multiplexed analog or digital data.
