amplifier
And we simulated the transmission model constructed with Erbium-doped fiber amplifier (EDFA) as the solo amplifier and the chirped fiber Bragg grating (CFBG) as the solo dispersion compensator used in the system.
      
The displacement of a piezoelectric multilayer actuator was amplified by a flexure-hinged amplifier based on the principles of triangle amplification.
      
A new electron beam (EB) control system was developed in a general vacuum EB machine by equipping it with an industrial control computer, programmable logic control (PLC), deflection coil, data acquisition card, power amplifier, etc.
      
This problem is of interest in connection with the possibility of application to the design of jet amplifier-one of the elements of fluidic automatic control (pneumonies) [1, 2].
      
The influence of a chain pumping reaction mechanism in a diffusion-type continuous-action chemical amplifier on an RF molecule is investigated.
      
It is shown that the efficiency of a chemical amplifier in a mode with partial fluorine dissociation is sufficiently high under the condition of the presence of a line with 0 ≤v≤5.
      
An analysis of the signal-to-noise ratio of a current amplifier
      
The signal-to-noise ratio of the current amplifier that includes a differenting delay line (50 ns) and an RC integrator is analyzed.
      
The amplifier is intended for use in conjunction with charge-, curret-, or voltage-pulse detectors, including those with large capacitances or low ohmic resistances.
      
The amplifier and detector can be connected with a long (in this work, up to 100 m) radio-frequency cable.
      
The root-mean-square intrinsic noise charge of the amplifier is 2.8×103e- when the input is nonloaded and 13.7×103e- when a 20-meterlong 3 cable is connected to the input.
      
The meter consists of a semiconductor magnetic-field sensitive double-collector transistor (magnetotransistor) with ferromagnetic concentrators of the magnetic field, differential amplifier, and digital voltmeter.
      
The magnetotransistor and the amplifier are built as a single silicon chip.
      
Noise Immune Charge Amplifier for Piezoelectric Accelerometers
      
A charge amplifier with active in-phase interference suppression is intended for investigations at impact loads accompanied by high-level noises.
      
To suppress low-frequency in-phase interfering signals, a compensation circuit with a differential amplifier is used, and, to suppress high-frequency ones, an input longitudinal transformer is used.
      
The sensitivity of the amplifier is 0.25 mV/pC, in-phase interference suppression factor is 40 dB at an input cable length of ~100 m.
      
A Two-Channel Power Amplifier with a Diplexer Output
      
To sum up the powers of two independent signals from a two-channel amplifier, a diplexer constructed with the use of small-sized directional couplers is used.
      
The amplifier-converter with a low level of input current noise (1.5 fA in a range of 0-1 Hz) provides photocurrent recording in the 116-dB dynamic range.
