the frequency of the synchronizing signal. To remedy this
deficiency, the examiner turns to Ishida. Specifically, the
examiner asserts (Answer, page 4) that "Ishida teaches using a
sampling signal to detect the received data in which the
frequency of the sampling data is higher than the frequency of
[sic] synchronizing signal (col. 6, lines 5-10)." The examiner
further explains that the preamble sampling signal is the
sampling signal and has a frequency higher than that of the data
transfer frequency fs, which is the frequency of the
synchronizing signal. We note that the examiner (Answer, pages
14-15) states that the phase synchronization signal 105
corresponds to the claimed sampling signal and bit
synchronization signal 106 corresponds to the claimed
synchronizing signal. Then, the examiner contends (Answer, page
4) that:
Since both Egawa and Ishida are in the same area of
using a synchronizing signal to recover data in data
communication. [sic] It would have been obvious . . .
to use a [sic] the sampling signal for detecting the
received data from the host computer in Egawa wherein
the frequency of the sampling data is higher than the
frequency of synchronizing signal as taught by Ishida.
The suggestion of doing this is to allow the received
data of Egawa to be properly decoded even if a noise is
contained in the received signal.
