Appeal 2007-3837
Application 10/631,897
1 2. The Examiner finally rejected claim 5 as being anticipated by
2 Christopher.
3 3. Claim 5 is as follows:
4 5. A decibel level adjustment device for calculating an output
5 signal which is a d decibel multiple of an input signal, comprising:
6 a plurality of signal lines arranged parallel to each other for
7 producing in advance signals that are shifted a number of bits
8 necessary for operating on said input signal;
9 at least one switch means for selecting outputs of said plurality
10 of signal lines or all “0”;
11 a switch control circuit means for receiving the value of said d
12 as a decibel control value and, in accordance with said decibel control
13 value, switching said switch or switches; and
14 an adder circuit means for adding together the outputs of said
15 switch or switches and output of said signal lines that does not pass by
16 way of said switch or switches.
17 Christopher
18 4. The Examiner found that Christopher describes in Fig. 6, a decibel
19 adjustment device including a plurality of signal lines (503, 504, 506, 508)
20 that are shifted a number of bits (Christopher, col. 9, ll. 12-14), at least one
21 switch means (510, 512, 514), a switch control circuit means (518, C0C1)
22 and an adder circuit means (516) (Final Rejection 2 and Answer 3).
