DIGITAL TRANSMISSION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The data rate defines the number of bits sent per sec-bps. It is often referred to the
A
bit rate
B
signal rate
C
baud rate
D
None of the above
Explanation: 

Detailed explanation-1: -Bit rate is a measure of the number of data bits (that’s 0’s and 1’s) transmitted in one second. A figure of 2400 bits per second means 2400 zeros or ones can be transmitted in one second, hence the abbreviation ‘bps’. Baud rate by definition means the number of times a signal in a communications channel changes state.

Detailed explanation-2: -Bit rate refers to the rate at which data is processed or transferred. It is usually measured in seconds, ranging from bps for smaller values to kbps and mbps. Bit rate is also known as bitrate or data rate.

Detailed explanation-3: -Bit Rate is the number of bits sent per second. The number of signal units per second is known as the Baud Rate. Bit Rate is calculated by multiplying the baud rate by the number of bits per baud. Baud Rate is calculated by multiplying the Bit Rate by the number of bits per baud.
