How about doing a little research, such as Googling: 3-to-8 decoder with enable?Considering the truth table of the decoder, only one output will be high at any time. Enable must be high for any output to be enabled. (If ENA is low all outputs will be low.)
You just NOW are FINALLY looking at your book!Ok i tried to made a little search. I looked at my book and i see in encoder with enable the decoder works when the E=0 and not work when E=1. So i guess my truth table when the Enable is E=1 everything stay as it is. Whn the E=0 then somethings change. But i still cant understand the truth table
Only if all of the signals are active-LO.Now i study better at one decoder 2-4 and with one enable input it says:
when enable is 1 the circuit not work and everything is one at outputs despite what is b2 b1 and b0. Also it says that when Enable is 0 the circuit work and only one output can be 0
so if am i right

Is this the right truth table?
