<TD width=3D634><FONT size=3D2>The RC5 code uses the bifase =
modulation technic=20
which means that every bit consists of 2 parts which are never the =
same.</FONT></TD></TR>
<TR>
<TD width=3D634><FONT size=3D2>So a bit is always a high/low or a =
low/high=20
transisition. By the RC5 code a 1 is a low high =
transisition</FONT></TD></TR>

<TD width=3D634><FONT size=3D2>The duration time of each bit is =
