Title: Digital multifrequency receiver
Inventor: HATANO TAKASHI
IPC: H04Q1/457
Filed: 1983-03-02
Abstract: PURPOSE:To eliminate the need for a filter by putting even a filter function in charge of a discrete Fourier transforming circuit. CONSTITUTION:Memories 36, 38, and 40 are read repeatedly at every time an eight-bit PCM signal is inputted to an input terminal 20, and the discrete Fourier transformation DFT of a combined body except of reference frequencies omega1 and omega2 and the frequencies of the multifrequency signal is performed. When the multifrequency signal is inputted, no DFT output regarding neither omega1 nor omega2 is obtained and the probability to obtain the DFT output regarding omega1 and omega2 as well as the DFT output of the combined body is high during voice input. The DFT output of the combined body is inputted to a latch 58 and compared with a threshold value by a detecting circuit 60; when the output is larger than the threshold value, it is judged that there is voice input, and the signal indicating that is inputted to a deciding circuit 50. A detecting circuit 48 inputs a signal to the deciding circuit 50 similarly. The deciding circuit 50 receives the outputs of the circuits 48 and 60 to output a signal indicating the presence of the multifrequency signal when the multifrequency is inputted and no voice signal is inputted.

Title: Display controller
Inventor: HORI TATSUHIKO
IPC: G09G5/00
Filed: 1993-01-29
Abstract: PURPOSE:To easily change the setting of a display operation parameter. CONSTITUTION:When no correct screen is displayed on a display device 2 due to the inconsistency of the display operation parameter, an operator operates a switch 7. Plural display operation parameters are stored in non-volatile memory 4, and one of the display operation parameters is specified by identification data. The identification data is updated at every operation of the switch 7, and another display operation parameter is specified sequentially. By performing such operation, the correct screen can be displayed on the display device 2. Since the identification data stored in the nonvolatile memory 4 can be preserved after the power source of a display controller 1 is disconnected, the correct screen can be displayed on the display device 2 by applying the power source again.

Abstract: PURPOSE:To provide the MODEM which can determine a transmission rate being optimal to a circuit by single training. CONSTITUTION:When a training signal is inputted to an equalizer 1, a deciding device 3 derives a deviation between an output signal of the equalizer 1 and an ideal signal, and improves the equalization accuracy of the equalizer 1 by feeding back its deviation signal to the equalizer 1. When a sequence deciding circuit 8 detects the sequence at the time point when this equalization accuracy is stabilized, an averaging circuit 4 derives an average value of the deviation signal, and outputs it to a transmission rate deciding circuit 5. The transmission rate deciding circuit 5 compares and inputted average value and a threshold set in advance, determines an optimal transmission rate to be adopted, and outputs it to a training generating circuit 6. The training generating circuit 6 generates a training signal containing the data for showing the optimal transmission rate, and thereafter, transmits this training signal to the other party side from a transmitting circuit 7.
