ADC- Analog to Digital Converter

A chip that converts analog signals into a sucession of digitial numbers. In constant time intervals the current analog value is acquired and put out as a digital number.

Costas Loop

A circuit for demodulation of phase-modulated signals.

DRM Digital Radio Mondial

Transmission system for digital broadcasting.

FFT Fast Fourier Transformation

Fast method to calculate a spectrum.

FPGA - Field Programmable Gate Array

Programmable logic chip for the implementation of simple logic circuits as well as complicated processing and even complete CPUs.


An analog signal of limited bandwidth can be recovered from discreet samples if the sample rate is at least twice the bandwidth of the signal.

PDL - Programming by Deleting Lines

A kind of extreme programming where simplicity of program logic is achieved through consistent minimzation of code-entropy.

PLL - Phase Locked Loop

A control loop in which a local oscillator is adjusted to a reference oscillator in frequency and phase.

QPSK - Quadrature Phase Shift Keying

Digital modulation process that codes two bits each to four possible phases.

Simulation - Transpiration - Verification

Classic rule of three in research and development.


Physical phenomenon in which the electric resistivity of matter disappears.

Yttrium-Barium-Cuprat YBa2Cu3O7-x

Well-known superconductor - starts superconduction at 93 K.
