Description: Frequency Quadrature (FQ) is a method used in signal processing to represent signals. This approach is based on decomposing a signal into two orthogonal components, which are 90 degrees out of phase with each other. This allows for a more efficient and accurate representation of signals, especially in modulation and demodulation applications. FQ is fundamental in communication systems, where clear and effective transmission of information is required. By using frequency quadrature, more data can be transmitted within the same bandwidth, resulting in greater efficiency in the use of communication resources. Furthermore, this method is essential in the implementation of various communication protocols and in the design of systems that manage the interaction between hardware and software. The ability to accurately and efficiently represent signals makes FQ a valuable technique in the field of telecommunications engineering and digital signal processing.
