Abstract
A data acquisition system comprises a signal processing chain including an analog-to-digital converter (ADC) circuit configured to: produce a digital output from an input signal; detect a specified signal feature of the input signal; and change an operating condition of an additional circuit of the signal processing chain in response to detecting the signal feature of the input signal.
Claims20
A signal processing chain of a data acquisition system, the signal processing chain including:
- logic circuitry;
- a data interface;
- and
- an analog-to-digital converter (ADC) circuit configured to produce a digital output from an input signal and detect a specified signal feature of the input signal, and wherein the ADC circuit includes a clock generator circuit configured to provide an operating clock signal with a selectable frequency to one or both of the data interface and the logic circuitry, and change the frequency of the operating clock signal in response to detecting the signal feature of the input signal.
A method of processing an analog signal, the method comprising:
- producing a digital output from the analog signal using an analog-to-digital converter (ADC) circuit of a signal processing chain of a data acquisition system;
- detecting a specified signal feature of the analog signal using the ADC circuit;
- and
- changing, by the ADC circuit, a signal path of the signal processing chain connected to the ADC circuit in response to the detecting the predetermined signal feature.
A data acquisition device comprising:
- multiple analog-to-digital converter (ADC) circuits configured to produce a digital output from one or more analog input signals;
- means for detecting a specified signal feature of the one or more analog input signals;
- and
- means for synchronizing operation of the multiple ADC circuits in response to the detecting the specified signal feature of the one or more analog input signals.
