Abstract

aparelho e método de recepção [problema] o objetivo da presente invenção é manter boas características de recepção enquanto também reduzindo escala de circuito tão pequena quanto possível em um dispositivo receptor para receber uma pluralidade de ondas radiodifundidas de bandas de frequência diferentes. [solução] uma primeira unidade de processamento de alta frequência (320s, 320t) detecta uma primeira onda radiodifundida transmitida usando uma primeira banda de frequência a fim de extrair um primeiro sinal de alta frequência. além disso, uma segunda unidade de processamento de alta frequência (320t, 320s) detecta uma segunda onda radiodifundida transmitida usando uma segunda banda de frequência que é diferente da primeira banda de frequência a fim de extrair um segundo sinal de alta frequência. então, pelo menos um oscilador local (320) gera um sinal de oscilador local usado na primeira unidade de processamento de alta frequência e na segunda unidade de processamento de alta frequência.
