Apparatus and method for automatic selection of broadband frequency channel using double frequency conversion |
摘要 |
An apparatus, method and readable medium capable of automatically selecting a channel of a broadband frequency and calibrating a frequency change using approximated frequency mapping function are disclosed. The apparatus comprises a frequency band dividing part; a frequency converting part; a first controlling part; and a second controlling part. The second controlling part selects a coefficient of an approximated frequency mapping function for a channel corresponding to a channel conversion selection signal from outside from previously stored coefficients of approximated frequency mapping function for the divided frequency.
