| Abstract: | An approach for designing digital-intermediate frequency(IF) receiver is introduced,the principle analysis and deduction of all parts of the receiver are performed including design of available-band filter,Analog-to-Digital Converter(ADC),digital orthogonal transforms based on digital polyphase filter,decimation filter,baseband signal processing unit. Finally parameters of the receiver are obtained. |
