摘要

A frequency-voltage converter device, with visualization by luminescent diodes, characterized in that it comprises: an input circuit; a voltage stabilizing circuit, intended to supply a stabilized voltage from an external power source; a transforming step, for converting the input pulses of the signal to be measured into rectangular pulses of constant amplitude, prior to passing through a filter stage and a stable multivibrator; an inverter and amplifier stage; an integrating step, intended to supply, from said pulses, already amplified, a direct current signal; a plurality of luminescent diodes and at least one integrated circuit of row control of said plurality of luminescent diodes, said at least one integrated control circuit, to be activated by said c.c.
