Okay, here is another ultra-newby question. I have rigged up (somehow successfully) a series of amplifiers and "filters" that
produce a pretty clear signal. However after fiddling with the circuit (physically touching it with my hands) I've moved parts
around which has re-introduced a small amount of noise. If I touch the battery, the noise goes away.
Other than the obvious - like "you have no clue what you're doing" - why does touching the battery (it's a 9V - and I just have to
touch the casing - not the leads) filter out the noise? I've tried adding a capacitor across the leads but haven't been able to
detect in significant change when doing this.
