what is sampling resolution

• Sampling resolution is the number of bits required per sample

• Sampling resolution indicates the frequency range of a signal.
• Sampling resolution is the number of samples taken per second.
• Sampling resolution refers to the duration of a signal.

sampling rate

• The number of samples taken per second from a signal.
• The frequency of a signal in hertz.
• The total duration of a recording.
