What are the step response specifications? Answer : The step response of a system shows how it reacts when a step input (typically a sudden change in input from 0 to a constant value, like 1) is applied. This is commonly used in control systems ... how a system responds in terms of its speed, accuracy, and stability when subjected to a step input....

How does a parametric up-converter work in frequency translation? Answer : A **parametric up-converter** is a device used in frequency translation, which means it shifts a signal from one frequency to a higher frequency. It works by utilizing a nonlinear material ... The lower frequency is "shifted" up by the higher-frequency pump signal, enabling frequency translation....
