A forensic investigator is analyzing a smartphone to gather crucial evidence. To fully understand the device's working and data flow, he needs to comprehend the various mobile architectural layers. While examining the device's frequency conversion, the investigator focuses on which of the following hardware components?
Frequency conversion in mobile devices is primarily handled by the RF (Radio Frequency) part. The RF section of a smartphone is responsible for converting frequencies from one level to another, which is essential for wireless communication. This involves up-converting and down-converting frequencies to make information transmissible over airwaves and receive data from the network. Therefore, focusing on the RF part is crucial for analysis related to frequency conversion.
Every mobile device consists of an RF up-converter and RF down-converter, analog filter, and attenuators. An RF mixer is the basic component used for frequency conversion.
