50Hz sinewave oscillator controllable linearly with POT

[pcsandhya82]

Hi all,

How to generate a sine wave of frequency 50Hz +/- 10Hz controllable through a POT?

the amplitude can be +/- 5to12V, duty cycle 50%.

555 and 566 give only +ve wave forms, i need a wave with alternating polarity.

thanks.

What's a sine wave with a duty cycle <>50%? Do you need a sine wave or a square wave?

make a 555 circuit with transformer coupling/capacitor coupling.
