Compander yog siv hauv digital xov tooj tshuab, compressing ua ntej nkag mus rau analog rau digital converter thiab tom qab ntawd nthuav dav tom qab digital rau analog converter. Quantization yuam kev, cov teebmeem ntawm lub suab nrov tuaj yeem txo qis siv Compander.
Tus khub siv rau dab tsi?
Companding yog siv hauv digital xov tooj tshuab, compressing ua ntej nkag mus rau analog-rau-digital converter, thiab tom qab ntawd nthuav dav tom qab digital-rau-analog converterQhov no sib npaug rau siv ADC uas tsis yog-linear li hauv T-kab xov tooj uas siv A-law lossis μ-txoj cai companding.
Tus tub txib ua suab dab tsi?
Ib tug thawjcoj ua ntej compresses suab ntawm lub transmitter los ntawm ib tug ruaj compression piv ua ntej RF modulation. Ntawm lub receiver lub teeb liab yog ces nthuav los ntawm tib tus piv tom qab demodulation. Companders pab kov yeej lub suab nrov txwv nyob rau hauv nqaim bandwidth FM xov tooj cua signals.
Compander system yog dab tsi?
Lub npe Compander piav qhia txog ntau lub tshuab turbomachine, suav nrog ob theem compressor thiab nthuav dav. … Ib tug raug compander yog hluav taws xob lub cev muaj zog tsav thiab muaj peb compression theem thiab ib tug expansion theem, mounted rau ib tug gearbox thiab thav duab los tsim lub txias zog yuav tsum tau rau liquefaction txheej txheem.
Yuav ua li cas thiab vim li cas thiaj yuav tsum tau?
Rau cov cim suab digital, sib sau ua ke yog siv hauv pulse code modulation (PCM). Cov txheej txheem cuam tshuam nrog txo tus naj npawb ntawm cov khoom siv los sau cov cim muaj zog tshaj plaws (nrov tshaj plaws). Nyob rau hauv cov ntaub ntawv digital, companding txhim kho lub teeb liab-rau- suab nrov piv ntawm tus nqi qis
