Webmodulation is used. To do so, a modulation resistance connected in parallel with the antenna of the transponder is switched on and off at the clock rate of the signal to be transmitted. ISO/IEC 14443 specifies that the load resis-tor is keyed by a modulated subcarrier (fc = 848 kHz). The subcarrier itself is ASK modulated with the Manches- WebNov 10, 2024 · ASK (Amplitude Shift Keying) La señal ASK (también conocida como OOK) es una técnica de modulación digital en la que la información se encuentra modulada en amplitud.

What does "shift keying" mean in the context of digital modulation?

Web1.4 Amplitude-shift keying (ASK) In ASK, only the amplitude of the carrier signal is modified in modulation. The simplest version is on–off keying (OOK). In OOK, either bursts of a carrier wave are transmitted or nothing is transmitted depending whether the input message signal is 1 or 0. Other versions of ASK use differing (non-zero ...
