I hope I am asking this in the right section. I came across the term "baseline wandering". I am unable to understand it from the books. Can someone explain what it means? It would be great if you do so using examples. Thanks in advance!

Baseline wander is actually the effect where the base axis(X-axis) of any signal viewed on a screen(like CRO) appears to 'wander' or move up and down rather than be straight. This causes the entire signal to shift from its normal base. I believe it is caused due to improper electrodes (like rusted, or broken). It is very prominent while taking the ECG (Electro Cardio Gram) of the heart and thus may cuase incorrect results, so they take extra precautions in the machine to eliminate the baseline wander by using different techniques.
Hope my explanation is clear..😀

That was quit nice piece of explanation and of course it happens due to electrode malfunction. In simplest words,
Baseline Wanderring is repeatation of improprer pattern on screen due to electrode malfunction.

Thanks buddy i got it.

Neatly explained makru!
I saw CRO in my EDC lab, didn't got a chance to use. By the way what is meant by CRO?

CRO stands for Cathode Ray Oscilloscope. 😀

The severity of the baseline wander is dependent on the HPF cut-on frequency and the PSD of the signal around DC.
The output of the high-pass filter will have equal areas (a=b) above and below zero volts.
If the pulse repetition frequency is low compared with the time constant of the input circuit, we'll see some "droop" in the waveform, indicating the discharging of the input capacitor

Actually,I don't konw why "baseline shift " happen with the transport of constant 0/1 in network information transportation?
