At last,Fourth Semester Lab exams are here.I had my Electronic Circuits Lab today.Luckily I got ,perhaps the simplest of all, the RC Coupled Amplifier.The midband gain was required to be 30 and frequency response was also to be calculated.I was afraid if I would get the Tuned amplifier.All experimets involving an IFT has created problems ranging from open terminals to transistor being damaged,during the regular lab sessions.Such problems were not reported during the first day,but we cannot expect the same the next day.But the digital electronics lab was perhaps the worst exam in the 2 1/2 years at Govt College of Engg, Kannur.I thought that I would get the output at the first trial.The question was but a bit difficult.A synchronous counter to count 0-2-4-6-7-5-3-1-0 and repeat.The design for the D flip Flop inputs were simple but implementing those using logic gates drove me crazy.I had to use 6 ICs inluding the flip flops and a total of 84 pins and i had to use 66 pins out of them.but i feel a bit sad because i was the one who first left the lab for circuits lab but for this one i was the last.there were questions like 3 bit code convertor,counter t0 count 0-2-4-6-0 etc that needed just 1 IC and 4 ICs respectively.but as of now,that session is closed.As it is said,NO USE CRYING OVER SPILT MILK,i must leave it behind.Also there are marks for the design and circuit diagrams,fair record and viva...........not a complete disaster,but still.................................
