Voltage to Frequency Converter (V to F) with power supply and 1 meter (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12279
Indian Lab Suppliers supplies the Voltage to Frequency Converter (V to F) with power supply and 1 meter (C.R.) (Product ID: 12279) as part of its electronics engineering lab equipment range. It turns a DC input voltage into a square wave whose frequency rises in proportion to the voltage.
Quick Answer
An IC 741 integrator ramps at a rate set by the DC input, and a Schmitt trigger resets it each time the ramp reaches its threshold, so the pulse rate is proportional to the input voltage. A master-slave JK flip-flop (IC 4027) in toggle mode divides the pulses by two to give a square wave with 50% duty cycle. Students read the input on a 0-15 V DC voltmeter and the output frequency on a 6-digit frequency counter, and view waveforms on a 20 MHz CRO; the counter and CRO are not included. Internal supplies are ±15 V DC and 5 V DC, each 50 mA.
