90 Degrees Phase Shifter -
by DSPStore Staff |
|
 |
A number of signal processing
applications require the use of quadrature processing techniques,
that is, where quadrature waveforms (those which differ by a
constant 90° phase shift) are required. A wideband 90° phase
shift with constant gain is very difficult to realize in any
technology. Usually there has to be a compromise between phase
accuracy and gain accuracy, with some techniques providing perfect
phase quadrature but poor amplitude matching, and others giving
accurate gain but imperfect phase. The method presented here
uses the Hilbert transform which, when applied to a band- limited
signal, generates the exact quadrature of the waveform (i.e.
all components are phase shifted by 90°). more>> |

Demystifying
Sigma-Delta ADCs by
Dallas Semiconductor.
|
|
|
|
This
in-depth article covers the theory behind a Delta-Sigma analog-to-digital
converter (ADC). It specifically
focuses on the difficult to understand key digital concepts of
over-sampling, noise shaping, and decimation
filteringe.
Sigma-delta converters offer high resolution,
high integration, and low cost, making them a good ADC choice
for
applications such as process control and weighing scales. Designers
often choose a classic SAR ADC instead,
because they don't understand the sigma-delta types. more>>
