An
Introduction to Delta Sigma Converters -
by Uwe Beis.
|
|
|
|
When looking
for an introduction to delta sigma conversion I found that
most explanations were from a very theoretical point of view.
It took me a while to understand how Delta Sigma converters
really work. So I decided to write this introduction for
people who prefer circuit diagrams to reading abstract equations.
A delta sigma ADC or DAC always consists of a delta
sigma modulator which produces the bitstream and
a low pass filter. more>>

Let's
Have Some Feedback on IIRs - Part 1 - by
Michael Francis |
|
|
|
A large
percentage of filters implemented in the digital domain are
Finite Impulse Response (FIR) filters. These types of filters
are used over a wide range of sample rates, and are well
supported by various tools, software, and IP cores. Another
type of digital filter is the Infinite Impulse Response (IIR)
filter, which is not as well supported and is generally used
in the lower sample rates (i.e., < 200KHz). The IIR uses
feedback in order to compute outputs, and it is known as
a recursive filter. This article looks at various
IIR filter types and structures that are available . more>>
