I-Coefficient quantization

Ngenxa yomkhawulo wokujula kokufakwa kwedijithali, iphutha lokulinganisa liyavezwa kuzilungiselelo ezithile zesihlungi se-FIR. Isexwayiso sokulinganisa i-coefficient ebomvu singase sivele ekhoneni eliphezulu kwesokudla sesakhiwo, futhi ijika langempela lokuphendula lizohlelwa ngokubomvu.

Umhleli wezibalo

Umhleli we-equation ikuvumela ukuthi uchaze imisebenzi yezibalo engahleliwe ukuze uthole impendulo eguquguqukayo. Khetha kububanzi bezinkulumo ezivamile zezibalo ezihlanganisa i-trigonometric, i-quadratic, i-exponential, nemisebenzi ye-logarithmic. Okuguquguqukayo okungu-t kumelela isikhathi ebangeni elisuka ku-0 kuye kwezingu-1 zenani lengqikithi yamagagasi. Ungafinyelela izibalo ezisanda kufakwa ngokucindezela okuthi isithonjana. Ukufaneleka kwesibalo esifakiwe kukhonjiswa yi- futhi izithonjana ezivela kwesokudla sebhokisi le-equation.

Impendulo yangokwezifiso yomfutho

Okukhishwayo kwesihlungi se-FIR kuyisamba esinesisindo samanani okufaka akamuva kakhulu:

Ukuze ucacise isihlungi sangokwezifiso, kufanele unikeze umbhalo file equkethe ama-coefficients okuhlunga ekhompyutheni yakho exhunywe ku-Moku:Go. I file ingaqukatha kufika kuma-coefficients angu-14,819 ahlukaniswe ngokhefana noma imigqa emisha. I-coefficient ngayinye kufanele ibe kububanzi obuthi [-1, +1]. Ngaphakathi, lezi zimelelwe njengezinombolo zamaphoyinti angu-25-bit asayiniwe, namabhithi angama-fractional angama-24. Ama-coefficients okuhlunga angenziwa ngekhompyutha kusetshenziswa amabhokisi amathuluzi okucubungula isignali ku-MATLAB, SciPy, njll.
Amanye ama-coefficients angase abangele ukuchichima noma ukuchichima kancane, okwehlisa ukusebenza kwesihlungi. Hlola izimpendulo zesihlungi ngaphambi kokusetshenziswa.

Ukunikezwa kwamandla kagesi

I-Moku:Go Power Supply iyatholakala kumamodeli we-M1 ne-M2. I-M1 ifaka i-Power Supply eneziteshi ezimbili, kuyilapho i-M2 ihlanganisa i-Power Supply eneziteshi ezine. Finyelela iwindi lokulawula Ukunikezwa kwamandla kuwo wonke amathuluzi angaphansi kwemenyu enkulu.

I-Power Supply ngayinye isebenza ngezindlela ezimbili: ivolumu engaguqukitage (CV) or i-constant current (CC) imodi. Ngesiteshi ngasinye, ungasetha i-current nevoltage umkhawulo wokukhiphayo. Uma umthwalo usuxhunyiwe, i-Power Supply isebenza ngesethi yamanje noma isethi yevolthitage, noma yikuphi okuza kuqala. Uma i-Power Supply ingu-voltage limited, isebenza kumodi ye-CV. Uma i-Power Supply ilinganiselwe okwamanje, isebenza ngemodi ye-CC.
