Humming and noise in turntable output: Source of problem and solution
Рет қаралды 5,323
5 жыл бұрынA turntable repair teaches a fantastic lesson about EMI and its effects - without the need for an oscilloscope.
In this video, we have a noisy deck turntable in our hands, and we investigate the source of the problem.
Any floating metal near your circuit will act as a parasitic capacitor, which is fundamentally two metal plates in parallel. This may not cause a problem for all circuits, but what if the circuit has a sensitive analog input?

What value do you recommend to use for the capacitors? Should it be ceramic?

Firstly, thanks for the video. Is the purpose of the video to design kind of filter?

Hi, the real purpose is to experiment the effect of stray metals around the circuits we design. For this kind of noise, a simple bypass capacitor is enough - no complex filters needed. But to deal with the noise at the end of video (common mode noise) some extra work is necessary.
