ABSTRACT:
A frequency-voltage converter comprising a feedback frequency generating means associated with controlled means, a saw-tooth wave generating means, a current source for the saw-tooth wave, pulse generating means and sample-and-hold means, the frequency-voltage converter being characterized by further provision of supply voltage switching means for changing the feedback frequency of the controlled means by changing the voltage to be supplied to the current source to change the current from the current source and to thereby the slope of the saw-tooth wave from the saw-tooth wave generating means.
