MULTIBAND EQUALIZER, ERROR RATE MEASUREMENT SYSTEM USING THE SAME, ERROR RATE MEASUREMENT DEVICE, AND PATH SELECTION METHOD
First Claim
1. A multiband equalizer, comprising:
- an input-side transmission circuit having one end at which an input terminal to which a signal is input is formed, and the other end terminated by the input-side termination circuit;
an output-side transmission circuit having one end terminated by an output-side termination circuit and the other end at which an output terminal for outputting a signal is formed;
a plurality of high-frequency components that are provided in parallel between the input-side transmission circuit and the output-side transmission circuit and have pass characteristics different from each other, each high-frequency component including a power supply terminal to which a driving power supply signal is selectively input from an external power supply circuit; and
a transmission path that transmits a signal transmitted through the input side transmission circuit to the output side transmission circuit and that includes only the high-frequency component in which the driving power supply signal is input to the power supply terminal among the plurality of high-frequency components.

Abstract
A plurality of high-frequency components 12 that are provided in parallel between an input-side transmission circuit 10 and an output-side transmission circuit 11 and have pass characteristics different from each other are included, each high-frequency component 12 includes a power supply terminal 17 to which a driving power supply signal is selectively input, a signal transmitted through the input-side transmission circuit 10 is transmitted to the output-side transmission circuit 11 via a transmission path including only the high-frequency component in which the driving power supply signal is input to the power supply terminal 17 among the plurality of high-frequency components 12, and at least one of the plurality of high-frequency components 12 function as an equalizer that changes a frequency characteristic of the signal input to the input-side transmission circuit 10 due to the driving power supply signal being input to the power supply terminal 17.
