Abstract :
In the modern era marked by rapid advancements in communication technology, audio signal processing plays an increasingly important role. Various audio processing techniques are employed in applications such as data transmission, wireless communication systems, high-level audio processing, and more. This research focuses on the application of Multiplexing techniques to address the complexity of overlapping signal spectra. This study aims to design a signal merging system using Frequency Division Multiplexing FDM. The primary emphasis of this research lies in the design of two key components: the Summing Circuit and the Channel Group Filter. In the Summing Circuit design, operational amplifiers op-amps, specifically LMH6730 op-amps, are employed to merge signals from three different channels. On the other hand, the Channel Group Filter design utilizes a bandpass filter with a 4th order to process frequencies within the passband range of 96kHz to 500kHz. By merging these three channels, the system can create a 400kHz bandwidth, enabling more good signal transmission and processing for communication applications that require a broad frequency spectrum. This research significantly contributes into addressing the challenges of signal merging within diverse frequency spectrums, with the potential to advance communication technology and signal processing in the future.
