Hey guys/gals - i am wondering if there are any members here who could help in designing a filter for my circuit.
let me elaborate, i am trying to filter down a 25khz pwm signal to a variable amplitude sine wave using an lc filter.
I was wondering if there are any off the shelf emi filters that would offer a solution.
The reason i say this is a paper published by my university in which a student uses an EMI filter for just this purpose, though he states it was an off the shelf filter rather than one composed of discrete components.
I will be looking into filter design so as to allow myself to compose an lc filter, but i was curious about a simpler readily available solution.
I have the feeling this is a silly question.
I apologize for my ignorance to the matter.
Any insight would be great.
Thanks
