· 49,152Mz:

o Frekansi tilannin laɲiniw: 48kHz (baarakɛlaw ka lamɛnni sariya), 96kHz, 192kHz.

o Formulaw:

§ 48KHz=49.152MHz ÷ 1024

§ 96KHz=49.152MHz ÷ 512

§ 192KHz=49.152MHz ÷ 256

o Frekansi tilannin laɲiniw: 44,1kHz (CD mankan ɲuman), 88,2kHz, 176,4kHz.

o Formulaw:

§ 44,1KHz=45.1584MHz ÷ 1024

§ 88,2KHz=45.1584MHz ÷ 512

§ 176,4KHz=45.1584MHz ÷ 256

AV anpiliyatɛriw (misali la, Denon AVR{2}}X8500H) ka kan ka bɛn ni fɛrɛnsi fila nunu ye walisa ka bɛn ni Blu{4}}ray (48kHz) ani CD (44,1kHz) kɔnɔkow ye.

3. Mobili lamɛnfɛnw ani minan minw be se ka ta ka taga yɔrɔ bɛɛ .

· -mobili kɔnɔ, tagamasiɲɛw dilanbagaw (DSPs):

49.152MHz ka 48kHz tagamasiɲɛw bɔ, ka Jitter dɔgɔya min be sɔrɔ in-mobili ka kuran yɛlɛmani fɛ.

· DAC ka tulolanw (i n’a fɔ, iFi Audio Hip-DAC):

45.1584MHz kristaliw minw fanga ka dɔgɔ, u don ɲɔgɔn na walisa ka 44.1kHz lamɛnni bɔyɔrɔ lamɛn ka ɲɛ telefɔniw kan.

## 3. Fɛɛrɛw sangali ani sugandili jateminɛw .

Sugandili ladilikanw:

· Filimuw ni telewisɔn/Streaming: 49.152MHz lo bila i ɲɛfɛ walisa ka bɛn ni 48kHz seriw ye.

· Mizikiw lamɛnni ani CD/SACD: 45.1584MHz sugandi walisa ka se ka dilan cogo ɲuman na.

· Sisitɛmu minw be bɛn ni cogoya caaman ye: Ka lɛrɛ fila - ta + FPGA yɛlɛmani barikaman (misali la, MSB Reference DAC).
