摘要： An equalizer includes a first delay module, a second delay module, a first amplitude module, a second amplitude module, and a combining unit. The first delay module receives a first signal and delays the first received signal for a preset period, and the first amplitude module transfers the first delayed signal to transmit a first weighted signal with a first peak amplitude. Similarly, the second delay module receives the first delayed signal and delays the second received signal for the preset period, and the second amplitude module transfers the second delayed signal to transmit a second weighted signal with a second peak amplitude. The combining unit combines an input signal and the first and the second weighted signals together to generate an equalized signal.

摘要： An exemplary port reducing method is for removing unselected ports of an original S-parameter file and generating an optimized S-parameter file. The method controls a display unit to display a user interface to receive commands from a user in response to user operation; the commands comprise a calling command, a selecting command, and an executing command. The method obtains the original S-parameter file in response to the calling command Next, the method determines which of the ports of the original S-parameter file are unselected in response to the selecting command, and connects each unselected port to the ground through one terminal impedance. The method then generates an optimized S-parameter file that comprises only the selected ports in response to the executing command.
