Abstract
A real time digital trigger detection channel includes an event detector, a pulse former, a low pass filter, an analog-to-digital converter (ADC) and a Discrete Fourier Transform (DFT) processor coupled in series. The event detector is responsive to an applied input signal and the presence of information requiring digital trigger generation. The pulse former generates a pre-determined, limited length, stable pulse signal which is applied to an anti-aliasing, pulse shaping low pass filter. The resultant shaped pulse signal is converted to a sequence of sample values by the ADC, which in turn are applied to the DFT processor, which in turn calculates a discrete Fourier transform of the output sequence of ADC samples, performing trigger position calculation based on values determined by the DFT processor.
