Some modulation methods are more immune to noise than others. Amplitude modulation methods like ASK/OOK and QAM are far more susceptible to noise so they have a higher BER for a given modulation.

The simplest form of amplitude modulation is to employ a system known as ‘on–off keying’ (OOK), where the carrier is simply turned on and off. This is a very elementary form of digital modulation and ...

There was a time — not long ago — when radio and even wired communications depended solely upon Morse code with OOK (on off ... carrier with voice AM or amplitude modulation is the oldest ...

As the name suggests, with Amplitude Shift Keying the amplitude ... more complex modulation schemes often can also do ASK and OOK modulation. ASK (Left) and OOK (RIGHT), both transmitting at ...

Radio Control /Remote Control and ASK (Amplitude Shift Keying) /OOK (On /Off Keying ... is much cheaper and easier to implement than the FSK (Frequency Shift Keying) modulation technique that is ...

Amplitude modulation (AM) is by far the oldest form ... They’re what we call on-off keying (OOK) or amplitude-shift keying (ASK) today. Even though AM is the first and oldest, it’s still ...

The Digital Imaging business unit presents at Photonics West their highly specialized Light Modulators, utilized for modulation of amplitude, phase, polarization and spectrum as well as for pulse ...

Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an analog telephone conversation, the voice waves on both sides are modulating the voltage of the ...
