Quadrature Amplitude Modulation (QAM)

Technology / Computers / Quadrature Amplitude Modulation (QAM): A method of modulating digital signals using both amplitude and phase coding. Used for downstream and can be used for upstream.

MTF (Modulation Transfer Function)

Entertainment / Photography / MTF (Modulation Transfer Function): A comparison of contrast between a test chart and the reproduced image. One of the measurements of lens performance used in the manufacturing process. MORE

Modulation

Entertainment / Music / Modulation: The process of changing from one key to another. MORE

Pulse Width Modulation (PWM)

Technology / Programming / Pulse Width Modulation (PWM): Is a way of simulating an analog output by varying high and low signals at intervals proportional to the value. MORE

Quadrature Phase-Shift Keying (QPSK)

Technology / Computers / Quadrature Phase-Shift Keying (QPSK): A method of modulating digital signals using four phase states to code two digital bits per phase shift. MORE

Quadrature Of Moon

Science / Tides and Currents / Quadrature Of Moon: Position of the Moon when its longitude differs by 90° from the longitude of the Sun. The corresponding phases are known as first quarter and last quarter. MORE
