The proposed circuit was implemented in the laboratory
using 74LS86 quad XOR IC and NMOS with total cost of
8Rs. It was found to work efficiently for a frequency of IMHz
tri angular signal with a peek voltage of 8V. This in effect
simulates a slew rate of 32V I j..Ls and can easily outperform an
op-amp window comparator circuit costing more than IOOORs.
The results of these laboratory experiments are given in Fig.6
and Fig.7.
