hi,
The R/C delay isnt on the manual switch side.?
Its down 'stream' of the R/C and RESET.
Do you follow, if not please ask.
Thanks Eric,for explaining it in abc.I understood all of it except for the down' stream' part which i guess is due to say more operations being performed on the Manual Switch side as compared to the Differentiator side?hence we get the Reset pulse before the switch pulse.
Yes. It is used for decoding when a single line can be mapped into any combination of segment(s) ON. Therefore it is possible to make a 7-segment displays nearly most of he ASCII characters easily. Or have a random display that goes from "1" to "5" to "2" to "8"....etc. Note only the display changes and there is nothing related to the actual inputs which usually is sequential.
You can get some info here where an 8-gang dip switch is decoded into 1~8 on a 7-segment display. Only one switch is ON at a time.

Thanks to you to LC,I am working on the link you provided.
