ABSTRACT:
A method and the device for voltage frequency transformation produce a fast, highly accurate voltage frequency transformer which has a wide frequency range. This method and device can be implemented with simple means. The discontinuous output signal of an integrating voltage-controlled oscillator (VCO) is transformed back into a constant voltage via a frequency divider. Then the result is compared with the input voltage (U.sub.E), and the result of the comparison is used to regulate the integrating, voltage-controlled oscillator (VCO).
