A sigma delta modulation loop circuit and related method is provided for use in a device having a radio frequency receiver. The loop is configured to compensate for noise that is generated by the sigma delta loop and that affects radio signals within the range of a radio frequency band ...
converter (DAC), and finally the analogue complex envelope signal is up-convertedto the desired radio frequency band by the radio frequency (RF) front end hardware.The SDR receiver down-converts the received RF signal using the RF front end, thecomplex envelope signal produced is then digitised...
A tuner can be switched between AM, FM, and stereo modes of reception without any radio or audio-frequency band-switching, and without any changes being made in the tuning meter connections. Separate AM and FM radio sections have power t... JAMES EDGAR KREPPS JR.,MEREDITH K. CHAMBERLAIN,RO...
