Re: types of capacitors

for coupling caps,must it be polarized? how to calculate the capacitance that i need for a particular circuit?

Re: frequency response

ok is it means that, if frequency get higher,then Xc will become smaller due to Xc=1/2πfC, then the gain of the op amp will become higher due to Rf/Ri right?? so the gain of the circuit depends on the frequency? But what is that mean the frequency? Is it the note we play or wat? Thx for help :applau...

frequency response

hi,got a question here. for a distortion circuit, there are always a series resistor with a caps in the negative feedback loop of an op amp, to determine the gain. the resistor and the caps there do something about frequency response right?if not wat is the use of caps there. can anyone explain me?

Re: Millenium bypass question

haha,peace peace :horsey:
i tink wat barcode trying to say is the Transistor serve the purpose as a diode with the emitter leg unused , IMO :roll:

Re: Millenium bypass question

emmm,i was confused :scratch:

tat means we only use the base collector junction of 2N3904 as a diode?
If correct,then where should I connect the emitter of the 2N3904?
Millenium 2 and C which one better?
