I have a problem of knowing the basic digital building blocks

With Analog building blocks i don't have a problem because when looking at a schematic of analog symbols and circuits/networks i can tell thats a summing mixer, differentiator, intergator, small single amplifier, pre-amp, poweramp, etc.

But with digital building blocks its more complex to know what the blocks are really cause its mixed up with all kinds of different gates,invertors,buffers,adders,subtractors,counters,flip flops etc.

Is there any turtorials or pictures of digital building blocks , so when i look at a schematic that has digital circuits i can BREAK up the schematic into BLOCKS

This is the adder stage, this is the subtractor stage, 4 bit count down counter circuit/stage, 4 bit synchronous Counter circuit/stage
,Asynchronous Decade Decimal 10 counter circuit/stage,3 bit up and down counter circuit/stage

Back in your 70's or 80's digital electronic classes or jobs , what stages/sections or blocks do u guys know of ?

I don't have a cookbook of digital building blocks but i'm trying to make one for myself

Just very simple building blocks for digital electronics

 

Take a look here:

do you know any others like that?

or any other turtorials for digital electronics ?

 

Back in the 60's, the basic building block was the NOR gate. A bit later, it was the NAND gate. You can make any logic function with either of those gates.

To be more practical, you should be able to get a data sheet for any logic IC with a diagram of the basic functions drawn out.

 

do you know any others like that?

or any other turtorials for digital electronics ?

I bet a simple search in google will reveal thousands of them.

 

oh yes i have done that

its kinda of hard what im trying to say

Since im not the designer of the digital circuits/networks or do R&D work at my job

I don't know how these digital circuits or networks are suppost to work or do

so i have just printed out digital building blocks from turtorials and tried to COMPARE them with the schematics to see it i can find any stages/sections/blocks that look similar or alike

Trying to break down digital circuits into Blocks is hard for me because the result or outputs of these are not the same as the ones in turtorials or electronic books

Truth tables tell up the inputs and outputs

But a digital circuit is many truth tables combined,mixed,splitted,arranged,added,subtracted

So i don't know how the logic signals are composed

Truth tables don't tell a tech. the "Intermediates signals" that are inbetween the inputs and outputs

the basic building block was the NOR gate and NAND gate

If you make a adder circuit out of NOR and NAND gates or a COUNTER out of NOR or NAND Gates manually

The truth tables will just tell you the inputs and outputs for individual NOR or NAND

The "intermediates signals" are all the 1's and 0's inbetween the inputs and outputs circuits that are either inverted,buffed,added,subtracted,flip,flop,etc.

It can be difficult to know what a block of logic circuits are doing if it's not apparent what the circuit is meant to do. You generally need an idea of the purpose of the circuit and the input and output signals to determine its function.

 

Go here to see a big slew of them...

Review so you know what tools can be in your toolbox. Then, when you have free time, look up datasheets on each to see what it does.

It is not important that you have everything memorized, it is only important to know how to find the crap you need.

 

You folks do realize that relicmarks (the OP here) has not made a post in the last 4 years?

Plus no one mentioned the classic book on logic building blocks:
