Hello,
What are possible causes of 50 kHz noise in a circuit? I built a simple inverting amplifier today using an LF356 opamp, but I persistently get a 50 kHz noise from the output on my oscilloscope. No amount of filtering seems able to get rid of it. Even when I remove call the capacitors from my circuits, leaving only non-reactive elements, this noise persists. It is something to due with my scope? Am I missing something? It's extremely irritating.
