Veelvoorkomende termen/afkortingen
AGC | Automatic gain control |
ATT | Receiver front end ATTenuator |
Carrier | A steady radio frequency signal that is modulated to add an information signal to be transmitted. |
DBF | DSP Bandpass Filter - enhances the receiver’s selectivity by allowing signals to go through it only if they are within a certain range of frequencies. It attenuates signals above and below this range. |
DNF | DSP Notch Filter - helpful in removing one or more offending carriers from the audio passband |
DNR | DSP Noise Reduction - enhances signal-to-noise ratio on weak signals |
DSP | Digital Signal Processor - |
IF Shift | Adjust the center frequency of the IF filter’s passband response. |
IPO | Intercept Point Optimization - bypasses the receiver preamplifier |
PSK | Phase Shift Keying |
RTTY | Radioteletype - Digital mode where radio signals sent from one teleprinter machine to another machine. |
SSB | Single Side Band - A common mode of voice operation on the amateur bands. Single-sideband signals use the upper sideband (USB -- that part of the signal above the carrier) or the lower sideband (LSB -- the part of the signal below the carrier). SSB transceivers allow operation on either USB or LSB. |
SWR | Standing Wave Ratio - A measure of the impedance match between the feed line and the antenna. |
TCXO | Temperature Compensated Crystal Oscillator - stable master oscillator so that the frequencies indicated by the radio's display are acurate and stable as the radio warms up. |
Watt | The unit of power in the metric system. The watt describes how fast a circuit uses electrical energy. |
