Device for generating a signal having a complex form by linear approximations

摘要

The present invention concerns a device for generating a signal having a complex form through approximation, by utilizing straight- lined segments having variable slopes. It mainly comprises a generator for generating a constant current supplying in parallel a capacitor and a circuit which varies the current i.sub.1 flowing through the capacitor. The variation of i.sub.1 influences the current flowing through the capacitor. The output signal sampled at the terminals of the capacitor is thus a sequence of linear segments, the slope of which is discretely variable, and controlled by the circuit for varying the current i.sub.1.
