EVALUATING
2920
APPLICATIONS
POTENTIAL APPLICATIONS CAN BE
DIVIDED INTO THREE CATEGORIES
Those which the 2920 can definitely do.
Those which It definitely cannot do.
(50kHz BW, or 90dB Dynamic Range)
Those which fall Into a gray area.
QUESTIONS TO ASK YOURSELF WHEN
APPENDIX
""
For many applications, the 2920 can either definitely be
used, or definitely not be used. However, sometimes it is not
clear whether a potential application can be done by the 2920.
Some examples which fall into this gray area are those appli-
cations where complexity/bandwidth constraints can't quite be
met, but it might be possible to sacrifice on one constraint to
meet the other. Or those applications where a very detailed
analYSis would have to be made, and a prototype program
actually written to determine applicability of the 2920. In many
cases where an entire application, as specified by the
customer, cannot be done with one 2920, part of it could be
done, reducing costs and component count sufficiently to give
the 2920 an advantage over another solution.
EVALUATING A POSSIBLE 2920 APPLICATION
Is 2920 dynamic range adequate?
The dynamic range with be 6dB/Blt for a total of 54dB
with a 9-blt conversion.
Does the bandwidth needed by the application under consld·
eratlon fall within the range the 2920 can handle?
Nominally 0-10 kHz, and up to about 15kHz.
Will the program length which Is required to obtain the
desired bandwidth allow for the Implementation of the
desired function or functions?
Will 40 RAM locations be enough?
Can the 2920 handle the I/O requirements with Its 4 Input
and 8 output channels?
