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: A microwave photonic multiformat jamming signal generation system is proposed and demonstrated. The proposed system demonstrates multifunctional deception jamming capabilities, including ...

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 ...

Chronic pain, defined as pain that persists for more than 3 months, is a major global health problem and affects as many as 100 million adults in the United States alone. Besides the suffering, ...

Abstract: In this letter, a direction-finding compensation method of nonideal modulation pulse for direction finding with the time-modulated array is investigated. With the transmission signal's ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...
