What is the frequency range categorized as 300 Hz to 3 kHz?

The frequency range categorized as 300 Hz to 3 kHz is identified as Medium Frequency (MF). This range is significant for various communication technologies, including AM radio broadcasting, which typically operates between 530 kHz and 1700 kHz but relies on the foundational principles established within the broader context of medium frequencies.

In the context of audio and telecommunications, the Medium Frequency range is critical for the transmission of audio signals, where clarity and intelligibility are important. MF frequencies can effectively penetrate the atmosphere and cover longer distances than higher frequencies, making them suitable for wide-area broadcasts.

Other frequency categories such as Very Low Frequency (VLF) and Low Frequency (LF) represent ranges below 300 Hz and are primarily used for specialized communications, such as maritime and submarine communication. Similarly, Super Low Frequency (SLF) describes frequencies lower than those typically categorized within the LF range. Thus, the classification of 300 Hz to 3 kHz as Medium Frequency is aligned with standard definitions in the field of frequency spectrum analysis.
