Detailed Description

template<class Tv = gam::real, class Ts = Synced>
struct gam::Impulse< Tv, Ts >

Band-limited impulse train.

This produces a Fourier representation of an impulse train where the number of harmonics is adjusted automatically to prevent aliasing. Due to numerical issues, this generator should not be used for producing very low frequency modulation signals. For that purpose, it is better to use the LFO class.
