This is digital part of an experimental RF receiver. It works with:
https://hackaday.io/project/182646-microwave-frequency-converter-0-3ghz-to-200mhz
https://hackaday.io/project/168985-microwave-synthesizer-4-7ghz
https://hackaday.io/project/187783-if-converter-228mhz-to-3mhz-and-lo-generator

This board includes:
- ADC with input amplifier
- some power supplies
- simple graphics controller for LCD implemented in FPGA
- signal processing implemented in FPGA: conversion to baseband, filtering, downsampling, RMS calculations
- microcontroller which controls the whole system, does calculations on the results from FPGA, controls keyboard and display.
