The maximum frequency of signal that can be accurately digitized is to be determined. Concept introduction: Nyquist criterion: To avoid a sampling error a signal must be sampled at the rate at least twice the maximum frequency component in the signal. Mathematically we can write f s ≥ 2 f c , where f s = sampling frequency. f c = highest frequency component in the signal.

Interpretation Introduction

Interpretation:

The maximum frequency of signal that can be accurately digitized is to be determined.

Concept introduction:

Nyquist criterion: To avoid a sampling error a signal must be sampled at the rate at least twice the maximum frequency component in the signal.

Mathematically we can write fs≥2fc ,

where fs= sampling frequency.

fc= highest frequency component in the signal.
