Given g1 and g2 are two enable pins. for the decoder to function, which logic value should we assign to g1 and g2? - in a decoder, basically we select one output (among all outputs) based on the inputs. suppose we set the enable pins correctly, and we set a = 0, b = 1, c = 0, d = 1, which output is chosen? - the chosen output is high or low? - now think again about the inputs that we have. given that the output number indicates the decimal value of the inputs, which input (a or b or c or d) should be considered the most significant bit? which should be the least significant bit?
