1. In control theory and signal processing, a transfer function where the degree of the numerator polynomial is less than or equal to the degree of the denominator polynomial, ensuring physical realizability and stability.
The engineer verified that the system had a proper transmission function before implementing the controller.
O engenheiro verificou que o sistema tinha uma função de transmissão própria antes de implementar o controlador.
2. A rational transfer function that approaches zero as the frequency approaches infinity, indicating that high-frequency components are attenuated.
For stability analysis, we need to ensure the transmission function is proper.
Para análise de estabilidade, precisamos garantir que a função de transmissão seja própria.
