· 49,152MHz ye:

o Frequency tilali laɲiniw : 48kHz (professionnel audio standard), 96kHz, 192kHz.

o Formulaw: 1 .

§ 48kHz=49.152MHz ÷ 1024. Bamako, Mali

§ 96kHz=49.152MHz ÷ 512. Bamako, Mali

§ 192kHz=49.152MHz ÷ 256. Bamako, Mali

· 45,1584MHz ye:

o Fɛrɛnkan tilali laɲiniw : 44,1kHz (CD mankan cogoya), 88,2kHz, 176,4kHz.

o Formulaw: 1 .

§ 44,1kHz=45.1584MHz ÷ 1024. Bamako, Mali

§ 88,2kHz=45.1584MHz ÷ 512. Bamako, Mali
