Analysis and performance Evaluation of trapezoidal filter in pulse shaping

The Implementation and realization of a digital pulse processor depends on the complexity of its software algorithms. Therefore, it is better to have simpler algorithms so that the possibility of straightaway use of them is provided. Based on recursive algorithms for real-time digital pulse shaping, exponential pulse is amplified and then digitized. Digital data are deconvolved and this deconvolved pulse is processed by a time-invariant digital filter which allows trapezoidal/triangular output pulse to be synthesized. Pulse shaping techniques used in trapezoidal filter are analyzed through MATLAB program. The new experiment shows how changes in parameters of pulse shaping algorithms affects the output waveform.
