???I have told you many times that i need design equations,still you say you don't know what i want.Thankyou for your info about capacitor.It works.I have some knowledge about circuit.But i want it to be clarified.If you had told me the working from a b c d,i can surely study those things and it will help me for my exam.Actuallt i dont have much time to get texts and study from that.i want to know how the circuit works as a telephone,receiving and sending info ,amplification etc.Ok thank you.I will not disturb you more. Bye,thank you
