Understanding
CIC Compensation Filters -
by Altera |
|
|
|
The cascaded
integrator-comb (CIC) filter is a class of hardware-efficient
linear phase finite impulse response (FIR) digital filters.
CIC filters achieve sampling rate decrease (decimation)
and sampling rate increase (interpolation) without using
multipliers.
A CIC filter consists of an equal number of stages of ideal
integrator filters
and comb filters. Its frequency response may be tuned by
selecting the
appropriate number of cascaded integrator and comb filter
pairs. The
highly symmetric structure of a CIC filter allows efficient
implementation
in hardware. However, the disadvantage of a CIC filter
is that its pass
band is not flat, which is undesirable in many applications.
Fortunately,
this problem can be alleviated by a compensation filter. more>>

Designing
a 256-Channel Digital Downconverter - by
Pentek |
|
|
|
As Software-Defined
Radio technology further penetrates large communication
systems for battlefield military radio networks, commercial
wireless systems, manned and unmanned aerial vehicles,
and monitoring facilities for SIGINT and COMINT, the need
to accommodate a large number of agile frequency channels
for radio receivers is quite apparent.
In each of these
applications, the same critical metrics apply: size, weight,
power, and cost for each receiver channel. Traditional
Digital Downconverter (DDC) ASIC devices feature only one
to four channels per chip, and straightforward implementations
of DDCs in FPGAs consume a significant percentage of available
resources. A new approach to DDC design takes advantage
of the parallelism of FPGAs to create a highly efficient
architecture for multichannel receivers. more>> |
