Description

Technical Field

[0001] The utility model relates to the technical field of signal processing devices, in particular to a signal processing device with a protective structure. Background Art

[0002] The signal processor is also called the channel processor. Its function is to receive the VHF and UHF frequency band broadcast television signals from the antenna, and then convert them to the channels specified by the working frequency band of the cable TV system after processing. In essence, it is a channel converter with more complete functions, more complex structure and higher indicators.

[0003] The existing signal processors have poor protection functions. After the signal processor is installed, when a heavy object falls from a height onto the signal processor, the signal processor will be damaged. In view of this, we propose a signal processing device with a protection structure. Utility Model Content
