Yes you are right! It's main appeal is that it is voltage controlled, hooking and oscillator up to it would be one way to create effects! One circuit I am interested to create is a variable lowpass filter. Thanks for the feedback!
Thank you for this video and the working of the jfet as a resistor in a linear way. An AGC for small signals using op amps will be possible. Very simple and straightforward and easy to learn and comprehend by the way you explained.
Thanks so much for making this video, it was super helpful! May I ask what model the JFET you used was? (If you still know) I'm trying to use this to make a Voltage-Controlled Wien Bridge Oscillator... I've devised a super complicated function generator to dial in precise resistance values, now I just need to find the best components to build it with
Hey Alt - Yes the JFET can be used as a voltage amplifier. If we set the JEFT circuit up to normally operate in the saturation region we can use it very effectively to amplify an input signal! Thank you for the feedback!
Isn't the "pinch off" voltage the highest (least negative) voltage where it conducts the least? I.e. maximum resistance, minimum signal output? You seemed to be saying it was the voltage where the JFET enters saturation, and conducts the most. What sort of dynamic range are we talking? Would the output go low enough to seem like it was shut off, or would there be a noticeable signal bleed?
Thanks for sharing. Looks like it might make for some interesting modulation effects in a synth.

Very informative. Thank you

Good video, but where is the schematic for the complete breadboard circuit, including the op amps?
Thank you for explaining this :) Which Transistors can be used in that way?
Excellent video, could this potentially be used to construct a Voltage controlled amplifier?

thanks!
Could i replace a resistor in a simple filter with a fet? would that make it a voltage controlled filter
Try it! Sounds like a good idea.
