Application Note MSA100

Microtrend Systems Development /Evaluation Platform P/N MS-3003 is an ideal low cost solution for a tutorial in Digital Signal Processing. It contains a 12 bit D/A with a software driver and sample code is available to generate a sinewave . All the user has to do is feed the 16 samples of the sinewave as input into the resulting recursive equations of each analog block..For the lead-lag filter below the scaling for the resulting recursive equation is left to the user.

All the resulting recursive equations have been obtained using the bilinear transformation with T=10ms. The notch filter below has the poles :

S1= - 29.8151149.

S2,3= - 12.918514 ± i x 15.921922373.
