Abstract
A signal modulation method, an adaptive equalizer and a memory storage device are provided. The method includes: receiving a first signal; performing a first modulation on the first signal based on a first power mode to generate a second signal having a first eye-width; performing a second modulation based on a second power mode to generate the second signal having a second eye-width; determining whether the first eye-width and the second eye-width meet a first condition; if yes, performing a third modulation based on the first power mode to generate the second signal having a third eye-width; otherwise, performing the third modulation based on the second power mode to generate the second signal having the third eye-width. Therein, a power consumption of performing the second modulation is less than that of performing the first modulation. Therefore, an efficiency of the adaptive equalizer may be improved.
