nounpl: imposed frequencies
frequência imposta
1. A frequency that is externally applied or forced upon a system, rather than occurring naturally or as a result of the system's own characteristics
The imposed frequency of the alternating current is 60 Hz in North America.
A frequência imposta da corrente alternada é de 60 Hz na América do Norte.
2. In engineering and physics, a frequency at which an external force or signal is applied to a system, causing it to oscillate or vibrate at that specific rate
When the imposed frequency matches the natural frequency, resonance occurs.
Quando a frequência imposta coincide com a frequência natural, ocorre ressonância.
3. In signal processing and communications, a frequency that is deliberately set or controlled by an external source
The radio transmitter operates at an imposed frequency of 101.5 FM.
O transmissor de rádio funciona em uma frequência imposta de 101,5 FM.
This is a technical term primarily used in engineering, physics, and electronics fields in both Brazil and the United States. It is essential terminology in academic and professional settings dealing with electrical systems, mechanical vibrations, and signal processing. The concept is fundamental in understanding AC power systems, which operate at standardized imposed frequencies (60 Hz in Brazil and North America, 50 Hz in Europe and many other regions).
