Abstract:
1. A self temperature-compensated high precision event timer, comprising: a measurement signal delay unit which converts a measurement signal into a pulse signal; a measurement signal integrator which converts an output signal from the measurement signal delay unit into a tooth-shaped waveform signal; a measurement signal analog-digital converter which converts an output signal from the measurement signal integrator into a digital signal; a reference frequency signal delay unit which converts a reference frequency signal into a pulse signal and has a same structure as the measurement signal delay unit; a reference frequency signal integrator which converts an output signal from the reference frequency signal delay unit into a tooth-shaped waveform signal and has a same structure as the measurement signal integrator; a reference frequency analog-digital converter which converts an output signal from the reference frequency signal integrator and has a same structure as the measurement signal analog-digital converter; a frequency multiplier which converts the reference frequency signal into a frequency signal needed to the measurement signal analog-digital converter and the reference frequency analog-digital converter; and an event time measurement controller which processes by a digital signal process method the digital signal outputted from the measurement signal analog-digital converter, thus computing a precision event time.
