Describe 74LS139 memory decoder.
The 74LS139 is a dual 2-to-4 line decoder. This contains two separate 2-to-4 line decoders - all with its address, output and enable connections.
The Pin-out of the 74LS139
Q. A low-pass filter circuit is shown in Figure. Using a PSpice program and PROBE, obtain the Bode magnitude plot for the transfer function ¯H(f) = ¯V out / ¯V in for the frequ
