Title: Receiver for digital radio communication
Inventor: OKADA KATSUTOSHI
IPC: H04J11/00
Filed: 1992-12-09
Abstract: PURPOSE:To make a frequency band of an IF signal coincident with a transmission band of a BPF by varying a frequency of a sine wave signal of a local oscillator till a synchronizing signal inserted in a communication signal at a sender side is detected from a demodulated communication signal. CONSTITUTION:A sine wave signal from an oscillation means 11 is integrated with an AC signal obtained from a received radio wave to obtain an intermediate frequency signal. Then the signal is subjected to quadrature demodulation at a demodulation means 13 via a band pass filter 12. A detection means 14 continuously monitors a demodulated communication signal and informs it to a control means 17. The means 17 changes a frequency of the means 11 little by little till the detection of the synchronizing signal is informed from the means 14. Thus, it is possible to make the frequency band corresponding to the required channel coincident stably with the transmission band of the band pass filter and undetection of a synchronizing signal in the communication signal is avoided.

Filed: 1990-11-30
Abstract: PURPOSE:To simultaneously practise plural modes with a set of plant simulator by providing plural data files and adding a means switching a flow of the signal between the data file and the characteristic program. CONSTITUTION:When an operator trainer 1 operates a process switch 5 on a CRT 3, the situation is stored in a data file 9 with an input-output device 8.

Next the process quantity is displayed on an indicator 4 and also a situation display lump 6 is turned ON/OFF. A switch 10 switching the signal 14 switches periodically the flow of the signal 14 between data files 9 and the characteristic program 11 in a cycle during which the characteristic program is practised in order of series A, series B, series C, series A and series B.... Hence with a set of plant simulator the plural operation conditions are simultaneously carried out.
