Dr. G V V Sharma introduced participating teachers to a problem solving model of teaching the basics of Digital Signal Processing (DSP). Teachers were given the problem of separating two sinusoids. The solution of this problem involves convolution, sampling, frequency response, impulse response and second order digital filter analysis and design, topics usually taught in a first course on DSP.
This solution was sought to be obtained by solving a series of problems through an intelligent mix of theory and MATLAB/SCILAB programming. Teachers were asked to solve the problems in groups. Interestingly all problems were solved by various groups.
The objective of this teaching methodology was to introduce a problem solving approach for teaching, that is likely to engage student interest and give them the confidence that comes from 'learning by doing'.
