Abstract
Abstract A wave reading apparatus comprising a wave generator (6,7) for generating a plurality of wave signals, a read-out frequency generator for generating a plurality of read-out frequencies, a controller (6) for controlling calculation, writing and reading of wave samples, a writing device (8), a plurality of buffer memories (10) and a plurality of read-out devices (5). The controller (6) informs requests of wave samples calculation to the wave generator (6,7) in accordance with the read-out frequencies. The calculated wave samples are written through the writing device (8) to the buffer memories (10) and read out by the read-out device (5) in accordance with the read-out frequencies at least one of which is different in frequency from the remainder.

Claim 1
Independent Claim
97 words
A wave reading apparatus comprising: a wave generator for generating a plurality of wave samples; a read-out frequency generator for generating a plurality of read-out frequencies; a controller for controlling calculation and writing, said controller informing requests of wave samples to said wave generator in accordance with said read-out frequencies; a plurality of buffer memories for storing said wave samples; a writing device for writing said wave samples into said plurality of buffer memories; and a plurality of read-out devices for reading out said wave samples from said buffer memories in response to said plurality read-out frequencies.
Claim 2
Dependent Claim
97 words
A wave reading apparatus comprising: a wave generator for generating a plurality of wave samples; a read-out frequency generator for generating a plurality of read-out frequencies; a controller for controlling calculation and writing, said controller informing requests of wave samples to said wave generator in accordance with said read-out frequencies; a plurality of buffer memories for storing said wave samples; a writing device for writing said wave samples into said plurality of buffer memories; and a plurality of read-out devices for reading out said wave samples from said buffer memories in response to said plurality read-out frequencies.
Claim 3
Dependent Claim
22 words
A wave reading apparatus as claimed in claim 1, wherein said writing device provides said wave signals to said buffer memories serially.
Claim 4
Dependent Claim
24 words
A wave reading apparatus as calimed in claim 1, wherein said reading device parallelly reads out said wave signals stored in said buffer memories.
Claim 5
Dependent Claim
30 words
A wave reading apparatus as claimed in claim 1, wherein said wave generator operates in time division multiplexed mode and generates wave samples in a predetermined calcula- ion time slot.
Claim 6
Dependent Claim
61 words
A wave reading apparatus as claimed in claim 1, wherein said controller has a plurality of calculation request flag registors which are set by the requests of wave samples in response to said read-out frequencies, inform occurrence of said requests of wave samples generation to said wave generator, and are reset by writing of said wave samples into said buffer memories.
Claim 7
Dependent Claim
36 words
A wave reading apparatus as claimed in claim 1, wherein said wave samples generated by said wave generator are written in said buffer memories as analog signals and said read-out devices read out said analog signals.
Claim 8
Dependent Claim
