Version 2 of the scale-bias module has come out as a really nice image-thrasher… I’ve made some conceptual errors, but I really like the results: So what’s wrong with this? I decided to go for an inverting configuration for the amplifier to be able to have gain smaller than 1 (could be useful for modifying […]

Some months ago we decided that internally, synkie’s signals should reference 0V for black (white is still not really defined, is it? 0.7V? 1V?) – while a standard PAL video signal has 0V for the sync pulses and black is somewhere around 300mV. Having complete black at GND simplifies a lot of further signal processing. […]
