Abstract
A signal generation circuit that uses a waveform generation mechanism to generate predetermined waveform(s) when triggered. A triggering mechanism is configured to repeatedly trigger the waveform generation mechanism at times that are dependent on data provided by a data source. The predetermined waveform may be a bandwidth-limited pulse, but might also be a rising edge or a falling edge of a pulse. Various consecutive waveforms may be summed together to thereby formulate a continuous signal. The waveform may have particular characteristics by design.
Claims30
A signal generation circuit comprising:
- a data source configured to provide data that is to be represented by a signal to be generated by the signal generation circuit and conforming to a particular protocol;
- a waveform generation mechanism configured to generate a predetermined waveform of one or more predetermined waveforms when triggered;
- a triggering mechanism configured to repeatedly trigger the waveform generation mechanism at a plurality of times by repeatedly performing the acts of identifying and triggering as follows:
- an act of identifying a time that the waveform generation mechanism is to be triggered based on the data received from the data source;
- and
- an act of triggering the waveform generation mechanism to generate a predetermined waveform at the identified time.
A signal generation circuit comprising:
- a data source configured to provide a data signal;
- a filtering mechanism configured to steep-frequency filter the data signal provided by the data source;
- and
- a driver configured to driver the filtered signal onto an in-vehicle network.
A method for configuring a signal generation circuit, the signal generation circuit including a data source configured to provide data that is to be represented by a signal to be generated by the signal generation circuit and conforming to a particular protocol, and a waveform generation mechanism, the method comprising:
- an act of identifying a waveform that is to be generated by the waveform generation mechanism;
- and
- an act of configuring the waveform generation mechanism to generate the identified waveform when triggered, wherein the triggering is dependent upon the data provided by the data source.
