Quadrature Amplitude Modulation

Quadrature Amplitude Modulation (QAM) is a technique used in telecommunications to transmit data efficiently. It combines two signals, varying both the amplitude (strength) and the phase (time position) of waves, to encode information. Think of it like a two-dimensional grid where each point represents a different combination of data. This allows QAM to send multiple bits of information at once, increasing the speed and capacity of communication channels, such as in Wi-Fi or digital TV. Essentially, QAM optimizes the use of available bandwidth for faster and more reliable data transmission.
