Digital and analogue modulation and demodulation scheme using vortex-based spin torque nano-oscillators

In conventional communications systems, information is transmitted by modulating the frequency, amplitude or phase of the carrier signal, which often occurs in a binary fashion over a very narrow ...

Enhancing the electrical readout of the spin-dependent recombination current in SiC JFETs for EDMR based magnetometry using a tandem (de-)modulation technique

Electrically detected magnetic resonance (EDMR) is a promising method to readout spins in miniaturized devices utilized as quantum magnetometers. However, the sensitivity has remained challenging. In ...

DMT (Discrete Multitone Transmission)

DMT oder Discrete Multitone ist ein Modulationsverfahren, um ein DSL-Signal (Digital Subscriber Line) zu separieren. Auf diese Weise wird bei ADSL der nutzbare Frequenzbereich in 256 unterschiedliche ...

ADSL-Modem

Für ADSL eingesetzte Modems verwenden das DMT-Modulationsverfahren. Neben der Modulation und Demodulation haben sie aber noch eine Menge mehr Aufgaben für ADSL zu erfüllen. ADSL-Modems werden an den ...
