How would wavefrom change change in time domain, frequency domain and

AI Thread Summary
Adding a DC level of 1 volt to a waveform shifts the entire signal upward by 1 volt in the time domain, resulting in a new baseline. In the frequency domain, the addition of the DC offset introduces a spike at 0 Hz, representing the constant component. The RMS value of the waveform will also increase, reflecting the added DC level, which can be calculated using the formula that combines the original RMS value with the DC offset. For example, if the original signal had an RMS of 2 volts, the new RMS would be approximately 2.24 volts after adding the 1 volt DC offset. Overall, the waveform's characteristics in both domains are altered by the introduction of the DC level.

Why don't you tell us what you think will change? Give us an example of a signal, and what it looks like in each of the domains you describe, and then add 1Vdc and tell us what you think will be the changes...
 

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
