Are there any type II Phase Detector / Comparator Modules?
Type II Phase Detector / Comparator compares two inputs and outputs in 3 states - +5v / 0v / -5v.
Just practicing my analog logic skills. I am trying to recreate / reverse-engineer Intellijel Rubicon’s tri-state wave using that. Also, I think a lot of PLL circuits like Benjolin, Wogglebug uses phase detector.
Please let me know.
don’t most phase detectors output a continuous voltage that represents the phase difference? PLL would never be stable if it output two or three discrete voltages, I don’t think.
It is not that simple.
Basically, there are two types of comparators. The Type I is a XOR gate, which is what you are mentioning, that just output +5v.
Type II outputs +5v or -5v depends on the phases of two inputs. e.g. left input comes first = +5v right input comes first = -5v otherwise, 0v
something like that
Frozen Wasteland have a module called Phased Locked Loop, but it doesnt have the type II Comparator I mentioned … I think I could use some logic module, attunuverters, switches and comparators to achieve this though …
ah, right. In actual use, of course, they are usually followed by an integrator or other LPF, making them continuous.
Seems working with two comparators
hmmm … no … cuz it compared with a DC voltage, changing pulse have no effect … I need to think of other ways …
My PLL has XOR and flip flop comparators (and their fuzzy logic relatives), but can always add more 
I have one not published that’s the CGS Slope Detector
I 've blocked my releases because just writing the release notes for the CGS INFINITE MELODY my brain farted
looking forward to the release of those. 
thank you all for the help! Much appreciated
