Question

Match the characteristics of digital and analog signals:

a. Discreet signal made of waves of different amplitude.
b. Data transmission can lead to deterioration or noise.
c. 10111000001.

Answer 1

Analog signals are discreet signals made of waves of different amplitude and vary continuously. Digital signals are represented by a sequence of binary ones and zeros, and they are discreet and have fixed voltage values.

Step-by-step explanation:

Digital signals and analog signals have different characteristics.

1. Analog signals are discreet signals made of waves of different amplitudes. They vary continuously and can represent a range of values. For example, the intensity values of sound or visual images are usually analog.
2. Digital signals are represented by a sequence of binary ones and zeros. They are discreet and only have two fixed voltage values, such as plus 1 volt and zero volts. Digital signals are used for data transmission because they are less prone to deterioration or noise compared to analog signals.

In the given example, "10111000001" is a binary sequence, which represents a digital signal.
