And if you want to stick with BLEP-like approaches, rather than BLEPs followed by an integrator you can use a pre-integrated BLEP, usually called a BLAMP (Band-Limited rAMP). This gives you a short waveform you can mix in any time there is a discontinuity in the first derivative of your signal, rather than in the signal itself.
By combining BLEPs and BLAMPs you can make an accurately bandlimited version of any signal that is piecewise linear -- including square/pulse, triangle, or sawtooth. -Ethan On Wed, Aug 8, 2018 at 12:12 PM, Frank Sheeran <[email protected]> wrote: > Hi Kevin, > > > I read at a couple of places if you use a leaky integrator on a Square > > then you can get a Triangle.
