High Frequency Generator Circuit
We get ours through a potentiometer.
High frequency generator circuit. This circuit generate sine wave oscillation. It is connected with the transformer with its lower end. Rf signal generators typically range from a few khz to 6 ghz while microwave signal generators cover a much wider frequency range from less than 1 mhz to at least 20 ghz. Some models go as high as 70 ghz with a direct coaxial output and up to hundreds of ghz when used with external waveguide source modules.
This circuit generate sine wave oscillation but actually we can modify the circuit to generate triangle or square wave function. The lm324 is a quad op amp meaning it s composed of 4 independent op amps. The circuit works on the principle of just using op amps. The frequency or repetition rate can be selected externally from 0 001hz to more than 300khz using either resistors or capacitors and frequency modulation and sweeping can be accomplished with an external voltage.
Like standard function generators the circuit allows for frequency adjustment. High frequency waveform generator is very useful in electronic experiment and design. High frequency waveform generator is very useful in electronic experiment and design. Ultrasonic pest repellent circuit last updated on august 12 2020 by swagatam 13 comments the explained ultrasonic pest repeller is a device that generates ultrasound or a very high frequency noise in the range of over 20 khz which becomes useful for repelling or scaring away animals like stray dogs cats mice bats etc.
The basic electrical circuit of a high frequency generator is analyzed next with focus on functional principles. High frequency waveform generator is very useful in electronic experiment and design. Special extra coil is placed vertically in the center of the great high frequency transformer. The icl8038 waveform generator is a monolithic integrated circuit capable of producing high accuracy sine square triangular sawtooth and pulse waveforms with a minimum of external components.
This circuit generate sine wave oscillation but actually we can modify the circuit to generate triangle or square wave function. The circuit can also easily allow for amplitude adjustment. The core of this waveform generator is max038.
