Power converters free system designers from unwieldy constraints, but the devices radiate unspecified fields that can destroy the signal/noise performance of sensitive circuits nearby. Magnetic-field measurements hold the key to finding and correcting these problems.

Performance-driven measurement instrumentation requires low-noise, high-bandwidth linear front-end circuits that combine with equally well-performing A/D...

Digital modulation and dynamic range
Microwaves & RF ; Measurement dynamic range is one of the essential performance parameters of a receiver or spectrum analyzer. Most published material, however, has addressed dynamic range in terms of sinusoidal signals rather than digitally modulated signals. While optimum dynamic range can be achieved by reducing
Use sound judgment with dynamic range.(THE DATA DETECTIVE)
EDN ; Almost everyone has heard the difference in the quality of sound produced by movie-theater system and that produced by home-theatre audio equipment. The difference can arise from audio-signal distortion that human ears can detect at low levels. Thus, rigorous testing must occur during product

Understand spectrum analyzers' dynamic-range specifications
Microwaves & RF ; The various interpretations of dynamic range are examined by using an analyzer specification sheet as a reference. ONE of the most important performance figures for a spectrum analyzer is the dynamic-range specification. However, it is also one of the most misunderstood and misinterpreted analyzer
High dynamic range amplifiers for cellular base stations. (Cover Story)
Microwave Journal ; Introduction The booming cellular and personal communications markets have created a tremendous demand for high quality RF components and subsystems. As the number of users increases, the systems must be adapted to handle the increased capacity requirements. Increased capacity and usage translates
Volume-unit meter spans 60-dB dynamic range.(design ideas)
EDN ; An audio volume-unit meter displays peak-related audio amplitudes to aid in accurately setting recording levels or for displaying an amplifier's operating conditions. A simple diode and capacitor network provides a classic volume-unit meter's peak-weighted response, but the circuit typically limits
Defining an op amp's dynamic range.(Technology Tutorial)
EDN ; IT IS EXTREMELY HARD TO DEVINE dynamic range for an op amp. A good place to start is with a DAC that defines dynamic range as the ratio of the maximum output voltage to the smallest output voltage that the DAC can produce (the least significant bit). You usually express dynamic range in decibels
A New Tool for Mass Analysis of Unknown Molecules: High-Resolution Multistep Tandem MS with Wide Dynamic Range Quantitative Analysis
Spectroscopy ; Mass spectrometers are effective for identifying and quantifying unknown molecules, such as disease-related proteins and small molecules in pharmaceutical researeh and medical diagnosis. In addition, mass spectrometry (MS) can be particularly powerful when analyzing molecules with complex
Dynamic range display.(Product information)(Brief Article)
Post ; VANCOUVER, BC -- At SIGGRAPH, BrightSide (www.brightside-tech.com) launched an extreme dynamic range display targeted at post apps. The dynamic range of an image is between its brightest and darkest regions. The DR 37P combines a matrix of LED backlights with an LCD panel offering 10x the
