Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
I suggest that the "sampling rate" column be expanded to indicate whether the device natively produces real or complex samples. For example, the Airspy R2 is shown with a 10 MHz sample rate. It actually samples at 20 MHz with a single (real) A/D converter, and the software driver can convert this to 10 MHz complex samples.
UHD provides portability across the USRP product family. Applications developed for a specific USRP model will support other USRP models if proper consideration is given to sample rates and other parameters. Several software frameworks support UHD: GNU Radio is a Free/Libre toolkit that can be used to develop software-defined radios. This ...
[a] But in signal processing, decimation by a factor of 10 actually means keeping only every tenth sample. This factor multiplies the sampling interval or, equivalently, divides the sampling rate. For example, if compact disc audio at 44,100 samples/second is decimated by a factor of 5/4, the
A typical choice of characteristic frequency is the sampling rate that is used to create the digital signal from a continuous one. The normalized quantity, f ′ = f f s , {\displaystyle f'={\tfrac {f}{f_{s}}},} has the unit cycle per sample regardless of whether the original signal is a function of time or distance.
HackRF One is a wide band software defined radio (SDR) half-duplex transceiver created and manufactured by Great Scott Gadgets. It is able to send and receive signals. Its principal designer, Michael Ossmann, launched a successful Kickstarter campaign in 2014 with a first run of the project called HackRF. [1]
Used in some DVB-T USB dongle TV receivers, namely the RTL-SDR ones used for software-defined radio. UART clock allows integer division to common baud rates up to 14,400(×16×125) or 28,800(×8×125). 29.4912 921600 UART clock allows integer division to common baud rates up to 921,600(×16×2). 29.50 SDTV
