| description | The utility model brings forward a high frequency signal filter circuit and a household electrical appliance, the filter circuit comprises a low frequency BJT filter module, a high frequency RC filter module and an intermediate frequency BJT filter module, the low frequency BJT filter module realizes low frequency band interference noise filtering, the high frequency RC filter module realizes high frequency band interference noise filtering, and the intermediate frequency BJT filter module realizes intermediate frequency band interference noise filtering. The intermediate-frequency BJT filtering module is used for filtering intermediate-frequency-band interference noise; by means of three-level filtering negative feedback control, amplitude deviation caused by interference noise in the high-frequency signal transmission process is avoided, low-cost and high-precision filtering is achieved through the double-triode amplifying and filtering circuit, the development efficiency of developers is improved, the deve |
