In 1938, the director of the Signal Corps Laboratories at Fort Monmouth, New Jersey, Col. Roger B. Colton, transformed ...

LoRa is a form of “chirp spread spectrum” modulation. The “chirp” signal sweeps smoothly across specific frequency range: usually 125 kHz, 250 kHz or 500 kHz wide. How long the sweep takes ...

[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

preventing signal attenuation and device failure. By integrating strain control and spin-polarized current control, the OSV devices can achieve efficient multi-state modulation, demonstrating at ...

(1) An earlier magnetic disk encoding method that places clock bits onto the medium along with the data bits. It was superseded by MFM and RLL. FM radio was invented in the early 1930s by Edwin ...

The Anritsu MG3710E is a cost-effective vector signal generator with up to two RF ports in a single unit. Each port can output RF signals with a frequency range of 100kHz to 6GHz and a maximum ...

Saelig Company, Inc. has introduced the Siglent SSG6082A-V Vector Signal Generator, which provides an output frequency range from 9 kHz to 8 GHz, with AM, FM, and PM analog modulation as well as pulse ...
