Abstract: A vehicular sensing system includes a sensor disposed at a vehicle and operable to capture sensor data representative of exhaust emitted by the vehicle during operation of the vehicle. A data processor processes sensor data captured by the sensor to determine a measured level of a pollutant present in the exhaust emitted by the vehicle. The vehicular sensing system, responsive to processing of sensor data captured by the sensor, determines that the measured level of the pollutant present in the exhaust is greater than a threshold level.

Abstract: A waveform generator for providing an analog output signal to a target device includes a look-up-table (LUT) that stores a plurality of binary address values and a digital-to-analog converter (DAC) that generates the analog output signal. The waveform generator receives an input trigger signal from the target device when the target device is ready to receive the analog output signal. The waveform generator generates a synchronized input trigger signal and aligns the analog output signal with the synchronized input trigger signal by reloading the LUT with a binary address value of zero.
