Hi there, I wonder if any one can advise me on my design of multiplexed digital display. My design uses 4 x BCD to a 16-to-4 multiplexer, that is then connected to a 4-to-7 decoder-driver then to 4-seven segment displays, then to a 4-to-1 multiplexer, phew! Is this as efficient as it could be? Does anyone have a better suggestion? Thanks!
