Abstract
The present disclosure relates to a signal measurement system, a controller and a method for digitally converting an input signal. The signal measurement system comprises an analog-to-digital converter (ADC) configured to receive the input signal and generate a plurality digital samples of the input signal. The signal measurement system also comprises a controller configured to control the number of digital conversions of the input signal performed by the ADC per unit time, based on at least one of a characteristic of the input signal and/or a digitally determined characteristic of the input signal, wherein the digitally determined characteristic of the input signal is based on one or more previous digital samples of the input signal generated by the ADC.
Claims20
A signal measurement system for digitally converting an input signal, the system comprising:
- an analog-to-digital converter, ADC, configured to:
- receive the input signal;
- and
- generate a plurality digital samples of the input signal;
- and
- a controller configured to:
- receive a characteristic of the input signal;
- receive a digitally determined characteristic of the plurality digital samples of the input signal, wherein the digitally determined characteristic of the plurality digital samples of the input signal is based on one or more previous digital samples of the input signal generated by the ADC;
- control the ADC based on the characteristic of the input signal and the digitally determined characteristic of the plurality digital samples of the input signal by using the characteristic of the input signal for initial adjustments of the ADC and using the digitally determined characteristic for subsequent adjustments of the ADC.
A method for digitally converting an input signal, the method comprising:
- an analog-to-digital converter, ADC:
- receiving the input signal;
- and
- generating a plurality digital samples of the input signal;
- receiving, by a controller, a characteristic of the input signal;
- receiving, by the controller, a digitally determined characteristic of the plurality of digital samples of the input signal, wherein the digitally determined characteristic of the plurality of digital samples of the input signal is based on one or more previous digital samples of the input signal generated by the ADC;
- and
- controlling, by the controller, the ADC based on the characteristic of the input signal and the digitally determined characteristic of the plurality digital samples of the input signal by using the characteristic of the input signal for initial adjustments of the ADC and using the digitally determined characteristic for subsequent adjustments of the ADC.
A controller configured to control a number of digital conversions of the input signal performed by an analog to digital converter, ADC, per unit time, based on:
- a characteristic of an input signal, wherein the input signal is input to the ADC for digital conversion;
- and
- a digitally determined characteristic of the input signal, wherein the digitally determined characteristic of the input signal is based on one or more previous digital samples of the input signal generated by the ADC.
