Einschaltautomatik für Endverstärker (Lautsprecher verzögert einschalten)

This frequency-voltage converter is dis- tinguished by its markedly linear conversion ratio. With the given component values the conversion ratio of the circuit is 1 V /kHz. If a DC voltage is applied to the input (0 Hz) then the output voltage is O V. The duty cycle of the squarewave input signal has no effect upon the conversion ratio.
