What is the role of RF tuning in Software-Defined Radio (SDR)?

The fundamental concept of RF tuning in SDR revolves around the digital processing of radio signals. Unlike traditional radios that rely on hardware components for each function, such as amplifiers or filters, SDRs handle these functions through software. This allows for greater flexibility and adaptability.

How does frequency modulation (FM) work within an SDR framework?

The FM signal is transformed into a digital format in the SDR receiver. The tuning process involves adjusting the center frequency of the receiver, similar to turning a dial on an analog radio. This adjustment helps in selecting different stations by shifting the center frequency.

What are intermediate frequencies (IFs) in SDR?

Intermediate frequencies (IFs) play a crucial role in the processing within SDRs. Each station is centered around a specific carrier frequency, and adjusting the center frequency through software allows for switching between stations. This feature provides more flexibility compared to hardware-based radios.
