FEATURES:
Spinning spheres test relativity’s subtlety
Gravity Probe B, the most precise experiment ever, will assess frame-dragging of the fabric of space.
By Bill Schweber, Executive Editor
Getting the most from Class D
multichannel audio amplifiers
Top-rate performance means understanding clocking, power supplies, and transistor-switching characteristics.
By Julian Hayes, Wolfson Microelectronics
Mixing it: DSPs and MCUs fall in together
Control processors and DSPs are being brought to meet cost and performance targets for a wide range of consumer and industrial tasks
By Graham Prophet, Editor
LEADING EDGE:
MEMS technology builds faster smart power chips
Device expands low-end, 32-bit performance
Signal analyser peers deeper into spectral data
Platform aids in streaming-video processing
Tiny capacitors are more complex than they seem
Catch software runtime errors at compile time
Is anybody there?
Quad signal processors top new mezzanine card
i-Pod-sized DMMs comply with safety ratings to CAT II at 600V, CATIII at 300V
Compact controller drives multiple motors
DESIGN IDEAS:
Quickly find pc-board shorts with low-cost tracer technique
Read isolated digital signals without power drain
MOSFET shunt regulator substitutes for series regulator
Zener test circuit serves as dc source
Gain-programmable circuit offers performance and flexibility
