Sample rate and data rate

Data rate is the speed at which bytes (or chunks of data) are sent down a channel. The bandwidth is how fast the bits that make up that data are transmitted. Sampling rate is the frequency at which an incoming signal is read to measure its shape. Take for example a typical 9600 baud serial connection.

What is sampling data rate?

Definition: Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.

What's the difference between sample rate and bit rate?

In summary, sample rate is the number of audio samples recorded per unit of time and bit depth measures how precisely the samples were encoded. Finally, the bit rate is the amount of bits that are recorded per unit of time.

Is sampling rate the same as bandwidth?

Sampling rate determines the sound frequency range (corresponding to pitch) which can be represented in the digital waveform. The range of frequencies represented in a waveform is often called its bandwidth.

What is the output data rate?

Output Data Rate (ODR): Rate (in Hz) at which new sensor data are available to the user. g: This is unit of acceleration for accelerometers: 1 g is equal to 9.80665 m/s2 °/s or dps (degree per second): This is the unit of angular rate for gyroscopes.
