tracing through digital circuits IC chips
When tracing through these components:
Encoders
Decoders
Flip Flops
Counters
Shift Registers
Multiplexer
Demultiplexer
How do u know if they are functioning properly? or how can i trace through each one of these components ? how would u guys do this to verify them?
Its hard to use a DVM meter or oscilloscope sinse they have multiple inputs and outputs , plus i would need alot of signal generators for the logic inputs , resets, enable inputs
All the new PCB's are surface mount IC chips so you can't use Logic clips or logic monitor because they are only made for dual in-line package IC chips not for surface mount or through hole IC chips
How can i "STEP" a counter and a shift register through a complete cycle and verify inputs, outputs, resets, clears, and other signals?
How can i "STEP" through a Encoder and decoder inputs and outputs?
The Encoders outputs are not binary but numerical or address lines? or LCD displays
So you can't use a DVM meter on the outputs of a Encoder or inputs of a decoder because its not logical binary states but numerical address codes? instead of using a DVM meter can i use a LCD display and probe the outputs of a encoder?
