I am doing one project in which I wanted to build an analog ckt which will generate sine wave of 20khz to 80khz & 80khz to 20khz continuously in sweep mode. Can anybody suggest me the ckt? Also I wanted to connect these signals to piezo-electric loudspeaker; I am not able to find the sources who manufacture such broad band and high frequency speaker. Anybody knows the source please?
Also, I wanted a model (lib) of XR2206 for proteus.
