In this paper we present an air quality measurement system that can be used to generate a map of the air quality in a city. The system is made of stations that can be attached to buses and taxis and gather data about air quality along the day as they travel in the city. Each station has sensors to measure the concentration of different gases, a position sensor (GPS) and a GSM/GPRS communication module...
It is shown here that the presence of phase noise or jitter in the test setup or in the ADC itself does not cause a bias in the transfer function estimation using the Histogram Test. the ADC parameters that are related to its transfer function are the transition voltages, code bin widths, integral non linearity, differential non linearity, gain and offset error.
In this paper we study the effect that additive noise and quantization noise have on the precision of estimates of amplitude, offset and phase at the origin of time of a sine wave fitted to a set of data acquired by a waveform digitizer.
