When you guys looks a schematic circuits for digital circuits/networks how do u do the circuit analysis for each inputs,outputs,etc for every pin on every IC chip?
When i look at a schematic i always thought it was just a topology of trace routing and schematic symbols of electronic parts ...
how can i build a simplier one? what can i use?
Added after 10 minutes:
using a logic analzer, which "mode" do i use to monitor the outputs of encoders and multiplexers?
Since the outputs of encoders and multiplexers are address code or encoded code you can't use a DVM meter or...
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...
capacitance phase angle lcr meter
The more reactance, the more phase shift
1.) Why is that more reactance the more the phase shift?
2.) a lossy inductor has low reactance and low phase shift?
3.) a lossy capacitor has low reactance and low phase shift?
what is the phase angle and how do i get it
The loss factor usually is defined as ratio of resistance to reactance (in series equivalent circuit), thus mathematically it's the tangent of a loss phase angle.
1.) So if i have a low dissipation the phase angle would be different than a High...
complex impedance lcr measurement
i don't understand this LOSS FACTOR in a capacitor or inductor
what does a loss factor do to a capacitor or inductor? does a loss factor change the phase angle?
Is a loss factor a leakage?
RF testing procedures such as power, gain, noise, RF power combining, RF switching and intermodulation
1.) What other RF testing procedures do u guys know or would do?
2.) How would u guys test for power,gain,noise?
3.) Using a RF power meter, what would be a bad power value VS a Good power...
lcr meter circuit
When using a LCR meter
Can you measure a RC network or a LC network or LR network?
Because my LCR meter just only lets me measure them one component at a time , i can't measure the network
The only way i can get the phase angle is using a dual trace oscilloscope when its a...
When troubleshooting digital circuits, most shorts are either stuck at VCC +5 volts or shorted to ground
example: of a digital circuit with a short stuck at +5 volts
Its hard to know if the short is on the input stages or output stages because all the stages of each IC chip inputs and...
Do you have to adjust the trigger knob on the oscillscope to display clock signals?
Why are the clock signals dependant on the oscilloscopes triggering?
because the signal is toggling and not sinusoid it makes the oscilloscope display a dead signal until you adjust the triggering
If i have a...
ya i tried the dip-switches but my fingers hurt after using them so much during testing
Because when testing digital chips that have multiple inputs and outputs i use switches to +5 for the inputs and Lamps/LEDS for the outputs
So i'm trying to find a box/unit that has a bunch of switches...
digital input output circuits
when testing 10 digital inputs , my test fixture uses 10 on/off switches to +5volts
when testing 10 digital outputs, my test fixture uses 10 lamps
who makes a box/unit that has a bunch of LEDs or lamps that are in parallel that have switches to turn off each Lamp...
