I am trying to make a Binary Calendar for a project. The O/P is a series of LEDs showing, in binary form, dd - mm - yy. I have chosen to use the MSF signal from the atomic clock in Rugby UK as the I/P, to make it super accurate. Bit pointless for a calendar but hey, it makes the system easier as there is no user I/P.
However, the MSF signal is BCD encoded! I have searched TTL and CMOS databases for a BCD-Binary IC. TTL used to do one it seems, but like with all fancy TTL ICs, it's discontinued. Does anyone know of a way to convert BCD to binary using regular combinational logic gates? Preferably using as little space as possible! Any suggestions would be most apprietiated! Thanks.
