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]
A GPS disciplined oscillator unit with a GPS antenna input, 10 MHz and 1 pulse-per-second (PPS) outputs, and an RS-232 interface.. A GPS clock, or GPS disciplined oscillator (GPSDO), is a combination of a GPS receiver and a high-quality, stable oscillator such as a quartz or rubidium oscillator whose output is controlled to agree with the signals broadcast by GPS or other GNSS satellites.

Earlier radio communication systems had to be made expressly for a given form of communications: telephone, telegraph, or television, for example. All kinds of digital communications can be multiplexed or encrypted at will. Digital cellular telephony (2G systems and later generations): GSM; UMTS (sometimes called W-CDMA) TETRA; IS-95 (cdmaOne)
A low-noise amplifier (LNA) is an electronic component that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio (SNR). Any electronic amplifier will increase the power of both the signal and the noise present at its input, but the amplifier will also introduce some additional noise.
Since the founding of the school in 1929, St. Andrew’s has been a boarding school that meets 100% of demonstrated need. In 2020-2021, student tuition cost was $62,150 for the 2021–2022 school year, with 47% of students receiving some form of financial aid. St. Andrew's granted approximately $7.2 million in financial aid in 2022–2023, with a grant average of $49,102.
Special drawing rights (SDRs, code XDR) are supplementary foreign exchange reserve assets defined and maintained by the International Monetary Fund (IMF). [1] SDRs are units of account for the IMF, and not a currency per se. [2] They represent a claim to currency held by IMF member countries for which they may be exchanged. [3]
