Question

Natural signals such as voice, music, or vision are analog in nature.
1. True
2. False

Answer 1

Hint: Signals are the scripted messages which are transmitted from the sender to the receiver and decoded for understanding. Natural signals are the signals which are produced in the natural world. It is hard to create all of the natural signals artificially.

Complete answer:
The signal is a function that tells about the information of a particular phenomenon. A signal may also be explained as an observable change in a quantity such as quantity. Signals are time-variant and they are used to transmit data from one point to another. Any quantity that can vibrate is used to transmit the message carried by a signal. Basically, there are two types of signals. One is analog and the second is digital signals.

Analog signals are the time-variant continuous signals. They represent the time-varying feature of the quantities analogous to any other quantity. Most of the analog signals are sinusoidal in nature.

A digital signal is a signal that is created from a discrete set of values of a physical change in the quantity that represent a sequence of sequences of values. In logic there are only two possible values of a signal 0 and 1. 1 is considered as high and 0 is considered as low.
The natural signals such as voice, music, or vision are continuous signals that have very discrete value projected through the continuous waveforms.

Thus the statement stated in the question is true and the correct option is Option 1.

Note:
A signal can be transmitted to a long distance. But while transmission of these signals it is necessary to take precessions so that there is minimum noise in the signal when it reaches the receiver's end. Signal modulations are also performed for the minimum noise and least losses.
