First-order correction for zero-order hold distortion in sampled-data filters
R.K.P. Galpin · Electronics Letters · 1969
Three 1st-order equalisers for zero-order hold distortion are described. Two, with z transform transfer functions, are suitable for applications with a variable sampling frequency. The other, for fixed sampling-frequency applications such as p.c.m., provides better equalisation with a simple RC network.
