Shahriar Posted February 12, 2006 Report Share Posted February 12, 2006 HiIn the following picture which belongs to a Tone Control Circuit, Can anybody tell me what that Small Value Cap (10pF) Is for? Between In+ & In- PinsI remind I saw the reason somewhere Once, but todayI looked it up in all my books, But did,'t find that. I guess it is some how related to OpAmp Input Capacitance?Thanx in advance Shahriar Quote Link to comment Share on other sites More sharing options...
audioguru Posted February 13, 2006 Report Share Posted February 13, 2006 I think the small valued cap stops problems caused by radio or TV pickup. Quote Link to comment Share on other sites More sharing options...
MP Posted February 18, 2006 Report Share Posted February 18, 2006 It is common to pick up a nearby radio station in tone circuits. 8 to 15pf is commonly used. MP Quote Link to comment Share on other sites More sharing options...
