Title: Amplitude modulator circuit
Inventor: KAWAMURA SHIGENORI
IPC: H03C1/00
Filed: 1978-04-28
Abstract: PURPOSE: To reduce the waveform distortion without using any filter by supplying the output delivered from the comparator to the control signal input end of the multiplier and then controlling the oscillator circuit so that the output of the comparator may be zero.  
     CONSTITUTION: The oscillator circuit consists of two pairs of integrating circuits using two units of operation amplifiers 1 and 2, one unit of operation amplifier 3 and multiplier 6 each. And absolute value (x 2  + y 2 ) 1/2  of the vectorial sum between sine wave output x and cosine wave output y is calculated instantaneously through arithmetic circuit 4 and then compared with modulation input signal e i  at comparator 5. Then the amplitude of the oscillation wave of the oscillator circuit is controlled via multiplier 6 to secure the difference of zero through the comparison at comparator 5. Accordingly, a quick response is possible to the change of the amplitude even in the course of one cycle, and furthermore no phase distortion is caused since no filter is used at the rear step.

IPC: H04B10/272
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To realize the system where a load of a controller is relieved and communication is made at a high speed. SOLUTION: In the case that data are sent from a terminal 3i, an optical packet transmitter-receiver 2i at a transmitter side uses a control information extract section 21 to extract control information denoting whether the data are multicast data or unicast data. A transmission reception control section 24 sends a control signal including an identifier denoting multicast data or unicast data to a controller 4 based on the extracted control information.  When the identifier indicates the unicast data, the controller 4 applies discrimination processing as to whether or not a terminal at a receiver side is receptible and sends a control signal to corresponding transmitter-receiver sets 2b-1 to 2b-n when the reception is available, In the case that the identifier indicates the multicast data, the controller 4 sends the control signal to all optical packet transmitter-receiver sets 2b-1 to 2b-1 unconditionally without discrimination processing as to whether or not the receiver side terminal is receptible.
