What is the equation for calculating bit rate?

To calculate bit rate, the correct equation is determined by the relationship between sampling frequency and sample size. The bit rate refers to the amount of data transmitted in a given amount of time, which is often expressed in bits per second.

When you multiply the sampling frequency (the rate at which samples of a continuous signal are taken) by the sample size (the number of bits used for each sample), you get the total number of bits generated per second. This calculation accurately reflects the data required for accurately portraying the sampled information over time, making it essential in contexts such as audio and video data transmission and storage.

Understanding this concept is crucial for optimizing storage and bandwidth requirements in digital media.
