Exactly. That is why humingi ako ng clarification.
Avoid using acronyms if possible para walang confusion.
MSI (medium scale integration) is a very old term. It is seldom used these days because even the simplest ICs, except TTL/CMOS 74xxx and 4xxxx devices, are almost all LSI (large scale integration) or higher. If you meant using these devices, sabihin mo na kaagad 74xxx TTL or 4xxx CMOS devices. Wala na yung pa MSI-MSI pa.
Walang ako schematic right now for a frequency counter but it is quite easy to cook up one out of decimal counters, octal latches and 7 segment display drivers.
decimal counter -> octal latches -> 7 segment display driver and some timing logic.
May schematic na po ako ng frequency counter and we're currently working on it..
ganito po sya.. may time base generator para sa isang input ng nand gate.. it composes of oscillators, frequency dividers, flip flops and controls for the reset and latch.. then dun po sa another input ng nand gate yung unknown frequency input signal
any suggestions po for latch and reset pag nareach na ng counter yung value ng unknown frequency signal
and yung about po sa input signal conditioning, okay lang po ba kahit hindi na lagyan? yung unknown frequency signal ko naman ay square wave naman galing sa 555?
para sa lahat po yung tanong
thanks, any help would be highly appreciated
