EEC 752 Electronic Circuit Design In this practical course students will carry out a design oriented project work using various analog/ digital building blocks which they have already studied in their analog electronic/ digital electronic courses such as Electronic circuits, integrated circuits and filter design. The project may include but not restricted to any of the following: . $. '. ). *. +. . 1.
!niversal op"amp based bi#uad !niversal %T& bi#uad &mplitude control or stabili(ation applied to any sinusoidal oscillators %p"amp/ %T& based function generator &ny application of log/antilog circuits &ny applications of analog multiplier/ divider &ny digital system design and its hardware implementation using TT-/ %0 Is &ny circuit idea 2not studied in the course3 using *** Timer in conjunction with any other Is
The above include . $. '. ). *.
