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]

SDR may refer to: Science and technology. ETSI Satellite Digital Radio; Selective dorsal rhizotomy, a neurosurgery; Short-chain dehydrogenase, short-chain ...
The DDR interface accomplishes this by reading and writing data on both the rising and falling edges of the clock signal. In addition, some minor changes to the SDR interface timing were made in hindsight, and the supply voltage was reduced from 3.3 to 2.5 V. As a result, DDR SDRAM is not backwards compatible with SDR SDRAM.
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]
Answer to Job (German: Antwort auf Hiob) is a 1952 book by Carl Jung that addresses the significance of the Book of Job to the "divine drama" of Christianity.It argues that while he submitted to Yahweh's omnipotence, Job nevertheless proved to be more moral and conscious than God, who tormented him without justification incited by Satan.
A rev 3 USRP1 platform, serial #140, with an attached TVRX daughterboard. Universal Software Radio Peripheral (USRP) is a range of software-defined radios designed and sold by Ettus Research and its parent company, National Instruments.
A higher SDR makes it less likely a social project will be funded. A higher SDR implies greater risks to the assumption that the benefits of the project will be reaped. A small increase in the social discount rate can matter enormously for benefits far into the future so it is very important to be as accurate as possible when choosing which ...
