  • Signal Conditioner Filtering Noise
    Signal conditioning modules, SCMs, used for measuring process control variables such as temperature, pressure, strain, position, speed, level, etc. are always subject to externally induced noise signals. Noise sources in the form of electromagnetically induced voltages (or currents) in industrial
  • Noise Reduction by Ferrite Cores
    In any current monitoring application noise may be capacitively coupled to the. outer shield of the current monitor. The coupled voltage causes current to flow. on the cable shield which in turn produces a voltage at the oscilloscope input. ground. This voltage appears as an erroneous part
  • Power Management in Noise-Sensitive Applications
    Itâ s best to take a careful, systematic approach when designing the power distribution system in noise-sensitive applications, like broadcasting, to ensure ideal performance. Not only does one need to consider all the usual parameters in a power management design, like input voltage, output
  • Environmental Noise Control Trends in Instrumentation
    1 Noise Control. Throughout the world, there is renewed effort to control noise levels in residential areas. High noise levels interfere with sleep and various human activities. In the long run it does not just affect the quality of life, but also causes physical ailments such as heart disease [1
  • Low-Voltage CMOS RF Frequency Synthesizers
    Low-Voltage CMOS RF Frequency Synthesizers. Containing three successfully demonstrated CMOS synthesizer prototypes, this book provides architectures that enable CMOS frequency synthesizers to operate at low supply voltages, and high frequencies with good phase noise and low power consumption.
  • AC Drive Motors -- Influence of Drive on Acoustical Noise
    The output voltage waveform of an adjustable frequency drive is not a sine wave but a series of square wave voltage pulses that result in a reasonable approximation of a sine wave current. Although there is an extensive history of successful use of standard motors on this waveform, the possible
  • Clock Division with Jitter and Phase Noise Measurements
    As clock speeds and communication channels run at ever higher frequencies, accurate jitter and phase noise measurements become more important, even as they become more difficult and expensive to manage. While measuring ultra low-jitter devices and equipment, the engineer is continually required
  • Keep Hybrid Powertrain Drives Noise-Free by Rejecting dV/dt Noise with Isolated-Gate Drivers
    in the high-voltage power inverters and other power supplies. This article will discuss the various sources of dV/dt noise in a hybrid powertrain drive and suggest several approaches to minimize the effects of the noise on the drive electronics.
