Notes: 1. The set-up time t
s
is defined as the minimum time that can elapse between L→H transition of the
modulus control input and the next L→H output transition to ensure that the
÷
16 (32) mode is obtained.
2. The release time t
r
is defined as the minimum time that can elapse between H→L transition of the modulus
control input and the next L→H output transition to ensure that the
÷
17 (33) mode is obtained.
