Cov tsis muaj lub suab processor feem ntau suav nrog cov hauv qab no:
Zaus teb: Cov lus teb zaus yog hais txog cov yam ntxwv amplitude-frequency, feem ntau yog raws li IF zaus, logarithm ntawm qhov sib piv ntawm qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ntawm qhov tso zis amplitude rau IF hauv qhov ntsuas zaus ntau, hauv dB.
Dynamic Range : Dynamic range yog lub logarithm ntawm qhov sib piv ntawm qhov siab tshaj plaws undistorted qib mus rau theem suab nrov, hauv dB. Qhov txawv ntawm qhov dynamic ntau yam thiab qhov siab tshaj plaws tso zis theem dB qhia lub suab nrov ntawm lub cuab yeej.
Distortion: Distortion feem ntau yog hais txog feem pua ntawm qhov tsis sib xws ntawm qhov tsis sib xws (harmonic distortion) ntawm lub waveform.
Common-hom rejection ratio: Qhov sib piv-hom kev tsis lees paub piv yog lub logarithm ntawm qhov piv ntawm qhov kev nthuav dav ntawm qhov sib txawv hom teeb liab ntawm qhov sib npaug ntawm cov tswv yim rau kev nthuav dav ntawm cov teeb liab hom, hauv dB. Ib hom kev tsis lees paub qhov sib piv siab qhia tau hais tias lub cuab yeej muaj kev tiv thaiv zoo dua rau kev cuam tshuam.
Cov tswv yim thiab tso zis raws: Tus naj npawb ntawm cov tswv yim thiab cov zis tawm ntawm lub suab processor yog qhov tseem ceeb. Piv txwv li, DP48 digital audio processor muaj 4 qhov kev tawm tswv yim thiab 8 qhov tso zis tawm, txhua qhov teeb tsa nrog 16-band parametric lim, nce tswj, lub rooj vag suab nrov, RMS limiter, faib, thiab ncua sijhawm.
Sampling zaus thiab quantization khoom: Sampling zaus thiab quantization bits ncaj qha cuam tshuam rau kev ua tau zoo ntawm lub suab processor. Lub DP48 digital audio processor muaj qhov piv txwv zaus ntawm 48kHz thiab quantization me ntsis ntawm 24 khoom.
Core nti: Hom thiab kev ua tau zoo ntawm cov tub ntxhais nti muaj qhov cuam tshuam loj rau tag nrho kev ua haujlwm ntawm lub processor. DP48 digital audio processor yog siv los ntawm Analog Devices 'SHARC ADSP-21489@400MHZ floating-point DSP processor.
Ua ke, cov kev txwv no txiav txim siab qhov ua tau zoo thiab daim ntawv thov scenarios ntawm lub suab processor, thiab cov neeg siv yuav tsum xav txog nws tag nrho raws li lawv cov kev xav tau tshwj xeeb thaum xaiv.
