put a double syncroniser (flop1 ,flop2)and connect the output of this to a 3 rd flip flop...
now use (a and ~b) logic at the output of flops 2 and 3
where a and b are outputs of flops 2 and 3
...
all the flops are synconosed to mainclk...
Thx, could u help me some more i am a new to all this i cant realy undersatn how 3 flip lops will help me to detected risiing ede and falling edge i need to detected both but on the same input .
thx.
a exor b can detect both rise and fall edge
a and ~b detects rise edge
~a and b detects fall edge
please draw the circuit and verify by drawing waveforms
