Dirac impulse response - June 2004, by Eric Juaneda

   A Dirac impulse is one value (1) followed and preceded by zero values. This function gives graphical digital filter response.

Theoretic Dirac impulse response
88.2kHz (x2) Mode
Real Dirac impulse response

   Showing Dirac impulse response is drawing function used to calculate interpolated samples in digital filter. The digital filter use a finite impulse response (FIR) program with Sin(t)/t function.
