ABSTRACT:
A circuit arrangement for linearizing the output signal of a measuring sensor by comparing this output signal with a periodically repetitive signal which represents the measurement characteristic to be linearized. Upon equality of the compared signals, the instantaneous value of a periodically repetitive second signal, which is a linear function of time, is transmitted to form the linearized measurement signals. According to a preferred embodiment, the periodically repetitive signals are produced by digital devices.
