I think this is what is happening: I use qAbs(m_ramp -1) to get the amplitude and that wraps when m_ramp is -32767. This happens at the very end of the ramp up period and injects a single sample of zero amplitude into the full output sine wave. This is making the distortion. I need to fix my ramp logic so that I don't have to subtract 1 from it. > > -- Joe, K1JT 73 Bill G4WJS. ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
