21 to 50 MHz 4rd order Low pass filter

Overview

The block is the 4rd order Butterworth low pass filter with cut-off frequency adjustment. It is based on the two amplifiers with feedback and has differential input and output. There are two modes for cut-off frequency programming: manually and automatically. The generator is used to adjust filter cut-off (CO) frequency in automatic mode. Also CO frequency can be set manually.
