Abstract
The embodiments herein provide a device and method to generate Pre-emphasized signal. In one embodiment herein an input file containing digital data representing a digital data pattern waveform is received and up-sampled by an Fs/Fd rate. The up-sampled digital data is used for generating step response. The generated step response is differentiated to generate coefficients of a pre-emphasis filter which are convolved with the digital data pattern waveform input signal to generate a pre-emphasized digital data pattern waveform file.
