:A: Analogue signal is very sensitive to level changes therefore any current toggling on the ground can become a signal super imposed to the real signal, digital has not this kind of interference but it does have time interference
—Analog digital hybrid modulation seeks the ways to eliminate the incoherent quantization noise component in digital communication, instead of conveniently making it minimal.

basic principle of analogue clamp meter
Well, yes they do. Any amplification adds noise to the signal. Some of this can be removed but the effects are cumulative. Imagine making a copy of a piece of music by an analog technique. Then making a copy from that copy, etc. You get more and more noise added to the system, even when the amplification is one. In digital systems, the music (or whatever) is made of bits that are either there or not. Cleaning up the bits is very easy. Perfect copies are typical.
1-What are the advantages of sampling analog signals?2-what are the following terms mean : instantaneous Sampling , Natural Sampling , and Flat-top Sampling ?3- what are the advantages of digital communication over analog communication ?4-Explain the reason for making the sampling frequency greater than or equal to (2B)Hz , where B is the bandwidth of the analog signal
Analogue
analog media means analog media.
I thank that antalog time is the time on a analog clock, It makes since analog time on a analog clock.
Analog
Analog signals can be received using an analog receiver.
Analog Modulation
To isolate a patient from getting connected to stray voltages. An isolation transformer is used and batteries power it to further isolate you from the real world. Also for sensitive measurements to eliminate some of the noise and current loops.
