Title: Automatic equalizer
Inventor: NARUKAMA KAZUO
IPC: H04B3/04
Filed: 1987-09-28
Abstract: PURPOSE:To realize an economical and excellent transmission characteristic by increasing the number of links of a stationary equalizer, and switching the number of links depending on long range and short range communication so as to retard and equalize the long range and short range communication. CONSTITUTION:An automatic equalizer corresponding to + or -3 link is used without any modification to select the number of links of a stationary equalizer 2. Then the number of links is switched selectively when the square mean error of a deciding device 4 of the automatic equalizer 3 is not converged. The automatic equalizer 3 is operated to minimize the square mean error of the device 4 by the adjustment of tap gain and since the tap gain is normally nearly + or -3 links as its limit, in case of the long range communication, even if the tap gain is adjusted to a maximum value, the square mean error is not converged. The tap gain limit and the square mean error are supplied to a control means to increase the number of links of the equalizer 2 to apply automatic equalization again, thereby applying optimized equalization. Thus, the delay equalizer effective to both the long range and short range communication is realized with economical and easy apply excellent transmission control by the automatic equalizer.

Title: Voice privacy telephone set
Inventor: NAKANISHI YOSHINOBU
IPC: H04K1/02
Filed: 1990-09-11
Abstract: PURPOSE:To correct a frequency error occurring in a transmission state and the change of a delayed variable in a simple circuit constitution by providing a frequency error absorbing function to a frequency shift circuit, i.e., a MODEM circuit which can control the carrier frequency. CONSTITUTION:A reception control circuit 117 controls dynamically the carrier frequency of a frequency shift circuit 112 to a higher or lower level. That is, the equivalent coincidence is secured between the period of the output signal of a reference noise generating circuit 114 and the priod of the transmission noise signal sent from the transmission side and serving as the input of an adaptive echo canceller 115. Thus the mutual delay relation between both periods can be kept in a fixed range. Therefore the circuit 112 functions as a frequency error absorbing function that secures the coincidence between the periods of two noise signals inputted to the canceller 115. Thus it is possible to correct the frequency error caused on the transmission line set between the transmission and reception sides and also to correct the change of a delayed variable in a simple circuit constitution.

Abstract: PURPOSE: To conduct frequency conversion without use of a local oscillation circuit by using a nonlinear characteristic of a semiconductor element, especially a intermodulation characteristic due to a 3rd harmonic distortion and extracting a modulation signal being superimposed on an oscillating signal oscillated in an intermediate frequency range. CONSTITUTION: When a 1st nonlinear element circuit 6 receives a equipment signal amplified by a 2nd amplifier circuit 5 and an oscillation signal from a 1st oscillation circuit 9, intermodulation is caused by a 3rd harmonic distortion of a nonlinear element 3 of the 1st nonlinear element circuit 6 and modulation of the same modulation angular frequency as a modulation angular frequency of a signal of the carrier frequency is applied to the modulation signal with a modulation component of the signal of the carrier frequency. An intermediate frequency (oscillated frequency) similar to that of a conventional conversion circuit is obtained from an intermediate frequency (oscillated frequency) output terminal 10 via the 3rd band-pass filter 7.  Thus, the oscillation circuit needing high stability is not required and various countermeasures for leakage of the oscillated signal are not needed.
