You are designing a system requiring the transmission of data. Your system must perform higher than ________ kHz in order to do so.

4 kHz is associated with the upper frequency limit of standard voice telephony (POTS), not the threshold required for data transmission capability.

8 kHz is below the defined 10 kHz data transmission threshold and represents an intermediate frequency not identified by the standard as the data capability boundary.

The telecommunications cabling standard defines 10 kHz as the minimum frequency threshold above which a system is considered capable of data transmission. Voice-grade POTS (Plain Old Telephone Service) circuits operate at frequencies up to approximately 4 kHz, while data-capable systems require bandwidth exceeding 10 kHz. This threshold is used in cabling and system design to determine whether the infrastructure supports data services beyond basic voice.

16 kHz exceeds the defined minimum threshold; while systems at 16 kHz do support data, the standard sets 10 kHz as the minimum qualifying frequency.

32 kHz is well above the minimum threshold and represents a higher-capability system, but the question asks for the minimum frequency required, which is 10 kHz.
