Here we have designed our own Impulse invariant response (IIR) filter. First wh have designed Butterworth Low Pass filter and High Pass filter and plot the magnitude spectrum using scilab.
Scilab was used as it is a open source software. Thus anyone can easily implement their mathematical model on scilab and analyse it.
The magnitude spectrum whicha was plotted after the input parameters provided by the us is in terms of Logarithmic scale on magnitude axis(Y-axis) and Frequency in Hertz(X-axis).
To ensure correct nature of the magnitude spectrum we have taken the values in a certain range.
After knowing the concepts of Digital signal processing, now it was time to apply those concepts on the dsp kit. In this experiment, we were given a general overview of programming on a dsp kit in assembly level language. The DSP kit used was TMS320f28375. Basic arithmetical,logical and shifting Operations were performed on the kit. The instructions for above operations were implemented and register values before and after the execution were observed and noted down.
Well explained

ReplyDeleteVery good explanation.
ReplyDeleteClarified the basics of IIR filter.
ReplyDeleteThe above filter may be stable astable..
