摘要:
A sampling system includes an input terminal for receiving a data signal having a signal component and possibly a noise component. A sampler samples the data signal at a sample rate set in responsive to a control signal. A noise detector detects the presence of a noise component, and if a noise component is detected, generates the control signal conditioning the sampler to sample the data signal at a first sample rate satisfying the Nyquist criterion for the data signal including the noise component, and otherwise generating the control signal conditioning the sampler to sample the data signal at a second data rate satisfying the Nyquist criterion for the data signal including only the signal component.
