ABSTRACT:
A method of obtaining a final signal of low harmonic content from a waveform consisting of individual amplitude steps approximating an original signal such as a measurement quantity or the like includes successively interpolating between the values of each two mutually adjacent ones of the individual amplitude steps over a period of time defined by the time spacing between corresponding points of the mutually adjacent steps.
A circuit arrangement for carrying out the method contains an integrator which has two storage devices on the input side; the one storage device is connected through a switch device through a further switch to an arrangement which transmits the individual amplitude steps. A control device is associated with the switches.
