** 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
