Patent ID: 8766740

Claim:
An equalizer for compensating transmission loss of electronic communication signals, comprising: a circuit board configured to transmit electronic communication signals; and a compensation module mounted on and electrically connected to the circuit board; wherein the compensation module includes a pair of input pins, a pair of output pins, and at least two resistors; the pair of output pins electrically connected to the pair of input pins, a first resistor of the at least two resistors electrically connected to the pair of input pins and the pair of output pins, and a second resistor of the at least two resistors electrically connected to the first resistor; and wherein when an electronic communication signal transmitted by the circuit board is received by the input pins, a first portion of the electronic communication signal is directly output from the output pins, a second portion of the electronic communication signal is reflected by the first resistor and transmitted back to the output pins to output, and a third portion of the electronic communication signal is reflected by the second resistor and transmitted back to the output pins to output.
