It is derived from a modulation scheme known as Minimum Shift Keying (MSK), which is what is known as a continuous-phase scheme. Here, there are no phase discontinuities because the frequency changes ...

Instead of the on-off scheme under which spark gap transmitters operated, continuous waves would be required ... identification of FM translator stations. Another modulation scheme similar to FM is ...

A carrier is basically a harmonic electromagnetic wave — a pure continuous sinusoidal wave with a single ... and that is how GNSS works. GNSS carriers are phase-modulated by pseudorandom noise (PRN) ...

Continuous Phase Modulation for GPS Codes: Reducing Out-of-band Emissions and Improving RF/DC Efficiency This article discusses a method of applying known continuous phase modulation (CPM) techniques ...

The following application note describes how to use the Zurich Instruments MFLI, a 500 kHz Lock-in Amplifier, for the purpose of measuring, stabilizing, and controlling the relative distance of two ...
