Scott Moor Lafayette CollegeAbstractIn the rush to fulfill all that they must do, our students often find little time or encouragement toindulge their curiosity. To encourage curiosity, to allow for the diversity of our students tastesand abilities, and to allow for creativity, I introduced a flexible system of small student definedprojects.

These relationships are not required in the statement of the extendedTellegen’s theorem that we propose. However, they are required in the analysis. The analysismay be carried out either in the time-domain or in the Laplace transform domain. The Laplacetransform domain equations corresponding to Eqs.

,general feedback block diagram. The equivalent transfer functions (pre-filter and feedback) areobtained by means of superposition. Then, all the blocks are reduced into a single transferfunction by means of the simplification formula: P(s)G(s)/(1+G(s)H(s)). The resulting transferfunction shows the gain for each configuration (-RF/RA for the inverting Op-amp and 1+RF/RAfor the non-inverting configuration) and bandwidth. It also shows that the Gain*Bandwidthproduct is constant for the non-inverting configuration, but not so for the invertingconfiguration. This approach is straightforward and insightful, specially for those students whohave previously been exposed to feedback theory and who have backgrounds in fields other thanelectronics.I

The first term in the"collect" command in Figure 5 divides the symbolic solution for ωL by the input ea. The"collect" command is used to group all of the terms with the same power of s in the solution forthe transfer function ωL/ea. Unfortunately the denominator of this transfer function is not in thebest possible form. Figure 6 illustrates some of the Maple commands that are available toreformat the denominator of the transfer function for better understanding. The "denom"command separates the denominator from the remainder of the solution for ωL. All terms arealso divided by LaJmJL, which was the coefficient of the
