An analog calculating apparatus in which an analog signal, which is a function of time and has been ( permanently ) recorded on a first channel track of a tape recorder is read out during a first run of the tape of the tape recorder and is multiplied by a first one of a set of coefficients at equal time intervals in a coefficient multiplier and recorded on a second channel track of the tape recorder. During the second run of the tape the analog signal read out from the first track is then multiplied by the second coefficient in the coefficient multiplier and added through an adder to the product read out from the second track, and the sum is then recorded on the second track immediately after the second track is erased, and this latter operation is then repeated.
