摘要： A phase synchronizing circuit, wherein two phase detectors are used in quadrature to detect the phase of an input signal and to avoid hang-up when the phase of the input signal changes abruptly by 180.degree.. The two detected phase signals are then multiplied by a locally generated reference signal and re-combined, so that a synchronized output signal having reduced phase jitter results. This circuit is also incorporated in an N-phase PSK system, where it is used as a synchronizer and not as a demodulator. In a receiver for such a PSK system, the frequency of the received signal is multiplied by N, the phase synchronizer circuit of the invention is then used to extract the carrier (at a N times higher frequency), and a divider is then used to convert the synchronized carrier provided by the synchronizer circuit of the invention down to the original frequency.

摘要： An improved bandpass filter circuit for selecting a relatively narrow band portion of an input sinusoidal signal. The improved bandpass filter circuit produces an output signal whose phase deviation from the input signal is substantially constant for small variations in the frequency of the input signal. The improved bandpass filter circuit in accordance with the present invention does not use feedback control in its operation and therefore is free from the inherent delay time of a tracking type bandpass filter utilizing feedback control in handling transitory input signals.

摘要： The present invention is intended to provide a call system which can authenticate a call initiation request from a proxy dial server apparatus with a caller number specified by the proxy dial server apparatus without adding special processing. In the configuration according to the present invention, proxy dial server apparatus first requests telephone server apparatus to call a telephone number of a user. In this event, proxy dial server apparatus uses the telephone number of the user as a caller ID. Upon receipt of a call request, telephone server apparatus transmits an authentication challenge to proxy dial server apparatus for authenticating the caller ID. Upon receipt of the authentication challenge, proxy dial server apparatus generates a response using a user ID and a password previously registered in association with the user's telephone. This results in successful authentication by telephone server apparatus, allowing a call to terminate at the user's telephone number.
