- Abstract:
- The random noise test of analogue to digital converters (ADCs) recommended by the IEEE 1057 Standard for Digitizing Waveform Recorders recommends the use of a triangular signal to stimulate the ADC under test. Here it will be shown that a sinusoidal stimulus signal can be used instead. This gives greater flexibility when carrying out the test and allows sine fitting algorithms to be employed to determine the initial phase of the two data records that need to be acquired. The knowledge of this initial phase can be used to align the two records and reduce the errors introduced by additive noise in the instant of acquisition trigger.
