IPC: H03G3/12
Filed: 1989-05-17
Abstract: PURPOSE:To suppress a distortion component caused in an electronic volume itself by inverting a distortion component included in an output signal with a feedback circuit so as to obtain a feedback input signal. CONSTITUTION:An input signal Vin is inputted to one input terminal of a 1st differential amplifier 4, the signal is amplified and outputted from an output terminal. Moreover, an output signal Vout is inputted to the other input terminal of the differential amplifier 4 as a feedback input signal Vfi via a feedback circuit 5. Then the output signal Vout is inverted by the feedback circuit 5 and inputted to the differential amplifier 4 as the feedback input signal while being properly amplified, then the output signal Vout is suppressed by the same differential amplifier 4 and the distortion component included in the output signal Vout is also suppressed. Then the distortion component in the feedback quantity to the differential amplifier 4 is suppressed while ensuring the gain of an electronic volume by regulating the amplification factor of a differential amplifier 7.

Title: Master station selecting system
Inventor: AKAIWA YOSHIHIKO
IPC: H04B7/24
Filed: 1986-05-29
Abstract: PURPOSE:To eliminate a conventional control station by generating a strength measuring request signal for a received power to all master stations from a slave station to be communicated and deciding a master station to be selected based on each reception power sent from the master stations and identification information in response to said request signal. CONSTITUTION:In selecting one of the master stations by a slave station 4, the slave station 4 sends a power strength measuring request signal to the master stations 1-3. The master stations 1-3 receive the sent signal from the slave station 4 to measure the power intensity. Then each master station, after the elapse of delay times T1, T2 and T3 selected at random, sends the result of measurement to the slave station 4 together with the identification number of its own station. The slave station 4 receives and compares the result of measurement from the master stations 1-3, selects the master station measuring the maximum power strength based on the identification number and informs the selection to the master station. The time delays T1-T3 are taken at random before the master stations 1 3 send the result of measurement to the slave station 4, because the sent waves of the power intensity measuring result are not collided with each other.
