[moved] using nor gate to display 1-9 to 7-segment
« on: February 28, 2006, 05:03:44 am »
tulong mga kapatid!!!
may project kami na dapat maka-display kami ng number 1-9 sa 7-segment display... pero ang gamitin lang ay NOR GATE...
baka naman may schematic na kayo... hehehe
pang finals na namin to...

ang NOR gate and NAND gate pwede mo sya i manipulate into OR, NOT and AND. so in other words kaya mo magbuo ng circuit na puro NOR gate lang basta ma calculate mo lang ang tamang boolean expression. or pwede ka rin mag K-map.
ang una mong gawin gumawa ka ng truth table, 4 inputs(BCD) and output mo is 7 for each segment sa 7 segment.

next... calculate mo ang boolean expression for each segment

last... gawin mo ang circuit with each operation(OR, NOT, AND) substituted by a NOR gate equivalent.

research ka sa "Universality of NOR gate and NAND gate" google mo

ask ko lng tol kailangan ba maimplement mo ito sa actual? kasi if i-aactual mo ito, kailangan mo rin ng counter mo and clock? di ka makagawa ng counter and clock using only nor gate, u need flipflops and pulse generator

i can help you email mo ako sa transistorc1845@yahoo.com

hahaha! eto tol. exercise lng namin yan... pero 14 segment ang ginamit namin anyways hanapin mo lng kng saang part jan ang pang 7 segment lng. sana makatulong. tama din pala, u need a counter lng kng gusto mo automated ang pag display ng numbers. try mo lng ulit. sana makatulong....  ;)
