How does a parametric amplifier achieve low noise in microwave circuits?

How does a lock-in amplifier extract weak signals from noise?
Answer : A lock-in amplifier is a powerful tool used to extract weak signals buried in noise by focusing on a specific frequency of the signal. It works based on a technique called *phase-sensitive ... signals are weak and mixed with noise, such as in optical, electrical, or even audio measurements....

How does a parametric up-converter work in frequency translation?

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....
