<p>A circuit network for the non-linear digital-to-analog conversion of a periodic pulse signal having a linear average value which depends on a digital value into a direct current signal, wherein said network has different charge and discharge time constants for the pulse signals and the smoothing filter, so that a non-linear relation is obtained between the value of the input signal and the amplitude of the output signal of the filter circuit. The input network includes in series a resistor and a capacitor, the resistor of which is shunted at least partially by a diode.</p> |
