Definition

1. Noun:
   • Intermediate frequency (IF): In physics and electronics, "trung tần" refers specifically to a frequency that is between low and high frequencies in a given system or context. It is a technical term used in radio, telecommunications, and signal processing.
   • Medium frequency (MF): In some contexts, particularly in older or more general technical usage, it can refer to the medium frequency band of the radio spectrum (300 kHz to 3 MHz).

Usage Examples

• Noun:
  • Mạch trung tần là bộ phận quan trọng trong máy thu thanh. (The intermediate frequency circuit is an important component in a radio receiver.)
  • Sóng trung tần được sử dụng trong một số hệ thống liên lạc. (Medium frequency waves are used in some communication systems.)

Advanced Usage

• "dòng điện trung tần": intermediate frequency current.
  • Kỹ sư đang đo dòng điện trung tần. (The engineer is measuring the intermediate frequency current.)

Variants and Related Words

• Tần số trung tần (n): intermediate frequency (IF).
  • Tần số trung tần thông dụng là 455 kHz. (A common intermediate frequency is 455 kHz.)

Synonyms

• Intermediate frequency (IF): the frequency to which a carrier wave is shifted as an intermediate step in transmission or reception.
• Medium frequency (MF): the band of radio frequencies from 300 kHz to 3 MHz.
