Appeal No. 1999-0016
Application 08/638,071
conventional image and speech processing techniques use
complex digital logic. Appellant points out that the use of
digital logic which employs very precise arithmetic processing
is not always needed in every speech and image
processing/compression application. Appellant points out that
simple analog devices and/or circuits can be used with some
amount of signal loss/noise without adversely affecting the
results of processing/compression. Appellant discloses on
page 5 of the specification that figure 2a shows a data
compression system in accordance with the present invention.
The system shows a transformation module with analog devices
22, a quantization module with analog devices 24 and an
entropy coding module 26.
Independent claim 1 is reproduced as follows:
1. An [sic A] data compression system comprising:
collector means for collecting said data;
a transformer coupled to said collector means for
transforming said data to generate transform coefficients,
said transformer implemented using analog devices;
a quantizer coupled to said transformer for quantizing
said transform coefficients to generate quantized
coefficients, said quantizer implemented using analog devices;
and
