My situation is , I make five D-flip-flop to make 5 thermometer code (due to Vernier TDC can use two pulse signal to generate thermometer code) ,

how to turn 5bit thermometer code turn into 2.5 bit binary code ?

another one is how to add 0.5b redundant bit to TDC?



sorry for my poor English , your answer can help me a lots , kowtow , thanks your holy reply , Thank you so much brother



Circuit consist of five D-flip-flop , top side have five delay Line ,down side five delay Line too , top side always always positive edge trigger first ( pulse wave)

in code , or in hardware,
a simple look up table is easiest for 5bits,
