Problems solved by technology

The adjustable equalizer can be used for attenuation compensation for signals above different frequencies, but the disadvantage is that its cost will increase with the size of its adjustable frequency range
Therefore, these two equalizers cannot take advantage of each other, and both have room for improvement.

Embodiment Construction

[0030] Please refer to image 3 , image 3 It is a schematic diagram of a multi-stage cable equalization device in a preferred embodiment of the present invention. The multi-stage cable equalizer 300 is mainly composed of a fixed gain device 310 and an adjustable gain device 320 .

[0031] Among them, the present invention expects to attenuate and compensate the main frequency band of the cable signal 330 through the fixed gain device 310, and then attenuate individual frequency bands of the cable signal 330 (for example, frequency bands with higher frequency than the main frequency band) through the adjustable gain device 320 compensate. And the purpose of the design of the present invention is: if the main frequency band of the cable signal 330 is attenuated and compensated by the fixed gain device 310 first, the individual components of the cable signal 330 can be adjusted by using the adjustable gain device 320 with a simpler structure and lower cost. Instead of perform...

Abstract

The invention relates to a multi-stage cable equipoise device mainly composed by a fixed type gain device being cooperated with an adjustable type gain device. The multi-stage cable equipoise device performs attenuation compensation on a main frequency band of a cable signal by the fixed type gain device, and performs adjustment on different individual frequency bands of the cable signal by the adjustable type gain device. The multi-stage cable equipoise device can has an advantage of elasticity during usage in a condition of low cost because of a design of the fixed type gain device being cooperated with the adjustable type gain device.

Description

technical field [0001] The invention relates to a cable equalization device, in particular to a multi-stage cable equalization device. Background technique [0002] When the network is gradually moving towards the era of integration of video, voice, and data transmission, the existing network bandwidth is simply "a drop in the bucket" and cannot meet the needs of users. However, the maturity of the broadband network will bring a new field for the Internet era. In the past, most of the information that appeared on the Internet was text and pictures, and there were few materials that would occupy a large amount of bandwidth, such as sound and video. But the broadband network will break through such limitations, and multimedia web pages will appear, and all materials have been digitized and can be accessed, edited, and reorganized at any time, constructing a new virtual society that is mainly visually oriented. Therefore, major telecom manufacturers are actively developing ne...
