PiMod Zero: Transform old TVs into RF video modulators based on Raspberry Pi Zero (schematic, source code, PCB, etc.)

Overview

PiMod Zero brings old technology back to life by allowing the Raspberry Pi Zero to display color or black-and-white video and play audio on vintage TV sets. It provides a super compact way to watch old movies, play retro games, display digital art or browse using any TV operating system that receives standard NTSC broadcasts on VHF channels 2 and 3 (55.25 MHz and 61.25 MHz).

In the past, you'd need a bulky RF modulator box to condition the HDMI signal from the Pi Zero. Now, with this handy HAT that snaps onto the top of your Pi Zero, no additional dongle is required. In fact, once the Pi is powered up, the only other cable you'll need is a coaxial cable to connect the PiMod Zero to your TV.

Configuring the Raspberry Pi to output composite video and stereo audio to the PiMod Zero is easy. Convenient scripts and thorough documentation will be available in our GitHub repository.

The order of signal amplification and filtering
Do all signals need to be filtered before amplification? If the noise of my signal does not distort the op amp after amplification, can I amplify it first and then filter it, so that the noise generat
