IPC: G01P3/80
Filed: 1984-12-27
Abstract: PURPOSE:To obtain a correlation type speedometer which enables accurate measurement even for the upstream side and downstream side detection signals changing greatly in the amplitude, by varying the amplification factors of amplification circuits on the upstream and the downstream with a plurality of comparators to hold the magnitudes of the first and second signals within an allowable input range of a multiplication circuit. CONSTITUTION:In a correlation type speedometer 19, as the amplitude of the upstream side detection signal 1a becomes larger, the amplification factors of amplification circuits 13 and 14 are controlled automatically with comparators CM11, CM12 and CM13 to hold the amplitude of the first signal 6a inputted into a multiplication circuit 9 within an allowable input voltage range positively in a wide range of the amplitude of the detection signal 1a from once to 16 times the reference amplitude while the amplitude of the second signal 8a is held within an allowable input voltage range. Thus, accurate measurement can be done regardless of significant changes in the amplitude of the detection signals 1a and 2a. This also assures a stable measuring operation free from any sharp changes in the detection signal 1a due to the action of delay circuits 16, 17 and 18.

Title: Transmission/reception circuit for dual mode communication equipment
Inventor: ISHIZUKA SEIJIRO
IPC: H04B1/50
Filed: 1990-10-19
Abstract: PURPOSE:To reduce the power consumption in the digital mode and to eliminate a need of a TR switch by providing first to third analog/digital changeover switches and a three-terminal isolator. CONSTITUTION:Analog mode/digital mode changeover switches 14 to 16 and a three-terminal isolator 18 are provided. In the digital mode, a transmission high frequency signal does not pass through separating filters 5 and 6 of large insertion loss but passes only a low pass filter 4 of small insertion loss and a three-terminal isolator 16 of small insertion loss, and therefore, it is unnecessary to intensely amplify the transmission high frequency signal by a transmission circuit 1. A reception high frequency signal passes not only the low pass filter 4 of small insertion loss and the three-terminal isolator 18 of small insertion loss but also separating filters 5 and 6 of large insertion loss, and therefore, the amplification factor of the high frequency amplifier in a reception circuit 2 must be raised, and the overall power consumption in the digital mode is reduced. Thus, the power consumption in the digital mode is reduced and a TR switch is made unnecessary.
