What is an Analog signal
flow?
Analog signals are the representation of time
varying quantities in a continuous signal. It could be varying + (plus) level
highs to –(minus) level lows.
The analog signal is creating by using magnets and
electromagnetic flux. As an example, inside a microphone a tiny coil is moving
through a magnet according to the sound it captures. In each and every time the
coil moves, it is going through a permanent magnetic field generated by the
magnet and creating a current flow through the coil. Depending on the sound it
captures The movement of the coil is varying and creating a different current
levels (various amplitude levels) in different time duration according to the
movement. These qualities of the signal can be identify by the next device
connected to the other end of the cable for recreating the same signal for
different purpose. Such as amplifying.
Simply an analog signal flow
is a current flow with different amplitudes in different time durations
according to the qualities of the input signal.
What is Digital signal
flow?
The digital signal is based
on samples and binary signals. Which means it counts the amplitude and the time
difference of the signal and converts them to 1(on position) and 0 (off
position). The sound levels in a digital audio signal are retained as digital
values captured during the analog to digital conversion. These amounts of snap
shots per second are called as sample rate. Higher sampling rate gives a
smoother signal pattern.
