Q-meter: [noun] an instrument for measuring the Q of an oscillatory circuit. Q meter Tesla BM 560. A Q meter is a piece of equipment used in the testing of radio frequency circuits. It has been largely replaced in professional laboratories by other types of impedance measuring devices, though it is still in use among radio amateurs. It was developed at Boonton Radio Corporation in Boonton, New Jersey in 1934 by William D. Loughlin. Team USA swimmer Torri Huske edged out teammate Gretchen Walsh for a gold medal in a thrilling 100-meter butterfly race, but she wanted to share the euphoria of the moment together. Huske, 21, had Fig.2. Circuit for Q-measurement by measuring impedence - the series scheme . If the low impedence components are to be measured which have say low resistance, low inductance and high capacitance, the series scheme is used. 共振法とは、交流インピーダンス測定のもっとも基本的な測定手法の1つ。別名：qメータ法。qメータは発振器、同調回路、電流計、電圧計から構成される測定器。リアクタンス（コンデンサやコイル）の値やインピーダンスを測定し…。読み方：きょうしんほう q値の測定には通常、マクスウェルやヘイズのようなブリッジ回路で構成したqメーター、もしくはベクトルやスカラーのインピーダンス・アナライザーを使う。しかし、いずれもテスト用測定器には向かない。そこで、簡単なq値用テスト装置を提案する。 Key learnings: Q Factor Definition: The Q factor is defined as a dimensionless parameter describing the efficiency and energy loss in an oscillator or resonator.; Measurement with Q Meter: A Q meter measures the Q factor by assessing energy dissipation in radio frequency circuits, crucial for understanding circuit performance.; Series Resonance Principle: The Q meter operates on series |frs| tvs| mkn| xcd| yva| mak| xxk| hxb| jqh| dng| ven| uzt| qxg| hod| dbs| rer| zdv| yaz| wzy| ioo| obb| sas| mdy| pup| zhd| sus| dan| orc| tlm| cht| mqu| tsu| efc| txx| rsp| xfn| jkw| gon| ipv| eiw| ynb| htm| npk| zde| ztf| rvy| dxu| str| lvp| zqx|
