Modulation and Demodulation
They can modulate outgoing signals for transmission and demodulate incoming signals for reception.
Signal Amplification
Transceivers can amplify signals for transmission, ensuring that they are strong enough to travel over long distances or through various media.
Frequency Conversion
Some transceivers can change the frequency of the signals, allowing for compatibility with several types of networks or devices.
Signal Encoding/Decoding
They often handle encoding and decoding schemes to represent digital data as analog signals for transmission and vice versa.
