EXCEL DIGI LAB

Being a teacher, my aim is to always encourage students and other colleague teachers to make optimum use of PC machine which one has purchased and full functionality of the softwares available with that machine. As an example, here I am illustrating use of EXCEL to learn Digital Electronics. One can verify Truth tables and study the working of various logic gates (AND, OR, NOT, EXOR, EXNOR, NAND, NOR), Various combinational logic circuits like Half Adder, Full Adder, Controlled Inverter, Multi bit adder, Multi bit subtractor, Multi bit adder Subtractor, Multiplexers, Demultiplexers, Shift Registers, Flip flops, Counters, Parity Generators and checkers using EXOR gates, Encoders, Decoders, Controlled Inverter using EXOR gates and their uses and many more, by entering inputs directly and verifying outputs at various intermediate stages. One can also study use of universal gates to build various logic functions with the help of this tool. These outputs are derived by using various functions built in EXCEL. This was demonstrated to teachers and students. This idea helps teachers to make subject more illustrative and interesting. It has been proved to be an excellent tool for innovative class room teaching. This can be used as a learning material for open source learning and distance learning and which can be further extended to any subject.
