Two zeners are used to clip both sides of AC signal. Clipping level is determined by rating of zeners used, which can be 6, 9, 12, or 15V depending on application. Ratio of R2 to R1 determines amplification. If long supply leads cause oscillation, connect 0.1-μF capacitors between ground and suρply ρins 4 and 7 as shown．－F.M.
