Abstract:
A multiple input-type and multiple signal processing-type device comprising:an input stage for receiving a plurality of different analog signal types; a down-converter for downwardly converting first signal types to a desired processing frequency range; an up-converter for upwardly converting second signal types to the desired processing frequency range; an analog-to-digital converter (ADC) for converting analog signals at the desired processing frequency range into digital signals; a time domain signal processing section connected to said ADC for performing time domain signal processing on the digital signals; a frequency domain signal processing section connected to said ADC for performing frequency domain signal processing on the digital signals; a user selector input for permitting a user to selectively activate one of said down-converter or up-converter, and to selectively activate one of said time domain or frequency domain signal processing sections; and a signal recognition processor for performing signal recognition to determine whether to selectively activate said down-converter or up-converter, and to determine whether to selectively activate said time domain or frequency domain signal processing sections.
