How you can use fourier analysis in the communication?

Fourier analysis is used in communication systems to analyze and process signals by decomposing them into their frequency components. This allows for the effective modulation and demodulation of signals, enabling clearer transmission over various media. Additionally, it aids in filtering out noise and optimizing bandwidth usage, improving the quality and efficiency of data transmission in applications such as radio, television, and digital communication.

What type of network medium is used by ISDN adapters?

ISDN (Integrated Services Digital Network) adapters typically use digital communication over twisted pair copper cables, specifically utilizing the BRI (Basic Rate Interface) and PRI (Primary Rate Interface) configurations. The BRI uses two 64 Kbps B channels and one 16 Kbps D channel, while PRI can support multiple B channels over a T1 or E1 line. This digital medium allows for the transmission of voice, data, and video over standard telephone lines, enabling high-quality communication services.
