Firstly, Can anybody suggest me the best way to produce a cos wave ( of same frequency and amplitude) from a sine wave.

Secondly , how can i add a d.c level to an a.c signal(sine wave) other than by using a diode clamper or by OP-AMP clamper.actually i want an exact signal clamped to a d.c level so the procedure should not involve the use of a capacitor
