After 30 years of refinements, mud-pulse systems transmit data more quickly and more accurately, through increasingly deep wellbores. Operators are pushing telemetry systems to transmit real-time data ...

Abstract: The interference fading, which is detrimental for signal retrieval in phase-sensitive optical time-domain reflectometry (Φ-OTDR), is analyzed in frequency domain, and a novel spectrum ...

Klystron modulators are key elements in free electron lasers. They provide high-voltage pulses to bias klystron tubes with energies of several hundred joules. Amplitude variations directly affect the ...

Abstract: The detectability of the symbol rate of a digitally modulated signal by a delay and multiply receiver is investigated. Two signal pulse types are considered: Nyquist pulses and rectangular ...
