Appeal No. 2001-0588
Application No. 08/609,308
Reference is made to the brief and answer for the respective positions of
appellant and the examiner.
OPINION
The examiner applies Hashimoto to the independent claim 1 as follows:
Hashimoto is said to disclose an intermediate frequency source comprising a
VCO 11 tuned to generate a first output frequency F1' having a frequency fr, where the
VCO 11 is frequency modulated by an audio waveform produced by a microphone, and
a frequency prescaler 12 for receiving the first output frequency F1' and generating a
second output frequency F1'/N, wherein N is greater than one. The examiner also
contends that Hashimoto discloses a loop (11, 12, 13, 14) producing F1' and mixing F1'
in a mixer M1 with a second output frequency RF waveform f1. While it is not clear
what the examiner means by “However, for clarification said second output frequency
being operable for mixing with a RF waveform” [Paper No. 15-page 3], we presume that
the examiner is not certain that Hashimoto discloses the claimed limitation of “wherein
said second output frequency is operable for mixing with an RF waveform” so the
examiner relies on Cheah. Cheah is cited as disclosing a low cost band transmitter with
a frequency prescaler 4 for receiving a first output frequency and generating a second
output frequency having a frequency value of f/N, wherein N is greater than one and the
second frequency is operable for mixing 6 with a RF waveform 7.
