Device and Method to Transform Discrete Voltage Pulses to a Phase-sensitive Continuous Signal | NIST

Title: NIST Develops Phase Sensitive Rate Meter for Real-time Pulsed Signal Processing

The National Institute of Standards and Technology (NIST) has developed a new device called a phase sensitive rate meter that can transform discrete voltage pulses into a smooth, continuous signal. This allows for real-time, phase-sensitive processing of pulsed signals without the need for data transfer to a computer.

Key points:
– The rate meter performs phase-sensitive detection on pulsed input signals
– It transforms discrete voltage pulses into proportional dc voltage levels
– Demonstrated performance at pulse rates from 2,000 l/s to 500,000 1/s
– Tested with single-photon detector signals and moving peak tracking
– Enables continuous, real-time processing without computer delays

This invention could have significant implications for quantum technologies, particularly in the area of single-photon detection and processing. The ability to perform real-time, phase-sensitive analysis of pulsed signals could lead to more efficient and accurate measurement and control systems in quantum computing and communication applications.
