摘要:
A noise reducing circuit for a receiver such as an FM receiver which is improved in noise reducing effect while reducing an unfamiliar feeling to and an erroneous operation of the receiver. The noise reducing circuit comprises fuzzy inference means for fuzzy inferring, using an input vector consisting of several factors defining a receiving input condition as a prerequisite, in accordance with fuzzy production rules provided by membership functions of the factors of the input vector, and a fuzzy controlling signal generating circuit for generating a fuzzy controlling signal for controlling a control object amount of any one of a separation control circuit, a frequency characteristic control circuit and muting circuit or each of any combination of the circuits in accordance with a result of inference produced by the fuzzy inference means.
摘要:
There is provided a circulating line branched from a solution or suspension tank and returning again to this tank through a pump (15) used to control the flow velocity at a constant level. A fluid temperature is measured by a sensor (16) in said tank or said circulating line (14) while a temperature of a heating sensor (17) employing so-called electrically heating method and placed in said circulating line is measured. Concentration of a given subject in solution or suspension is determined based on a temperature of the heating sensor or a difference between a temperature of the heating sensor and a temperature of the fluid.
