Qhov no yog qhia los ntawm kab zauv C=XPEAK ÷ XRMS. Rau qhov ntshiab sine yoj (Daim duab), lub ncov yog 1.0, thiab tus nqi rms yog 0.707. Yog li, lub crest yam ntawm ib tug ntshiab sine yoj yog 1.414 (1.0 ÷ 0.707).
Peak factor formula yog dab tsi?
Peak to Peak Value
Cov txiaj ntsig ntawm qhov zoo thiab qhov tsis zoo yog lub npe hu ua ncov rau tus nqi siab. Nws qhia raws li IPP los yog V PP Kev sib npaug thiab cov qauv rau Peak rau Peak Voltage yog raws li nram no: VP-P=2√2 x VRMS=2.828 x VRMS VP-P=2 x VP
Koj pom tus nqi siab tshaj li cas?
txhawm rau txiav txim siab qhov siab tshaj plaws ntawm qhov oscilloscope kab, qhov siab tshaj plaws ntsug sib txawv ntawm kab los ntawm kab nruab nrab yog ntsuas los ntawm qhov screen. Tus naj npawb ntawm kev faib yog muab ntau los ntawm Y nce los ntawm oscilloscope tswj.
Tus qauv rau daim foos yog dab tsi?
Daim Ntawv Qhia rau ntau yam sinusoidal waveforms yog raws li nram no: Rau sine yoj, nws yog π/2√2=1.11072073. Rau ib nrab-yoj rectified sine yoj, nws yog π/2=1.5707963. Rau tag nrho-yoj rectified sine yoj, nws yog π/2√2=1.11072073.
Vim li cas peb thiaj suav daim foos?
Tus ntsuas nruab nrab ntawm RMS ntawm lub nthwv dej thiab qhov nruab nrab qhov tseeb(piv txwv li 'rectified' nruab nrab) ntawm lub waveform yog lub npe hu ua daim foos, thiab yog txoj hauv kev yooj yim. xa mus rau 'distortion' ntawm waveform nrog rau nws cov cua sov. … Daim foos yog ib txoj hauv kev yooj yim ntawm kev qhia qhov kev sib txawv ntawm cov waveform.
