LOW BAND FILTER CIRCUIT OF MUSE SYSTEM

摘要

The filter consists of a horizontal broadband low pass filter part which takes the differential signal as an input for 1 frame and bandlimits it to 8 MHz in horizontal direction, a horizontal narrowband low pass filter part which takes the differential signal as an input for 1 frame and bandlimits it to 4 MHz in horizontal direction, and a vertical low pass filter part which is connected to the horizontal broadband low pass filter part and bandlimits the signal in vertical direction for dynamic detection of 1 frame in MUSE (Multiple Sub-Nyquist Sampling Encoding) receiver.
