VCVS 5/a errors #764

Closed Qwerty135246 closed 1 year ago

Qwerty135246 commented 2 years ago

When I try to make a VCVS that has the function a*(5/a), it comes up with the error: NaN/infinite matrix!

what's a*(5/a)? that's just 5 isn't it?

the expression a*(5/a) is undefined if a is 0.. that's why you're getting that error. the expression should not be infinite at any point, especially not at 0.

Thank you! How can I improve, I want to amplify the sine wave with an amplification peak of 5V

I'm confused about why you want to do that. I could come up with something, but it wouldn't be practical circuit so there wouldn't be much point. Are you trying to emulate a real device?

I’m trying to create some form of transmitter/receiver
