We also need to prevent harmful signals, meaning signals that may lead to destructive failure at the output. This is done by limiting the max duty cycle of the pulses as well as limiting the frequencies allowed. The duty cycle of the pulses is limited by choosing a maximum time THM the pulse is allowed to be high, this time is independent of the frequency. This means the preset max duty cycle is dependent on the frequency of the pulse. Limiting the frequencies allowed is done by choosing a minimum time TPM after a pulse goes high until X2 is allowed to go high again. How this can be implemented is not discussed any further in this thesis. But this thesis should give the basis for choosing maximum and minimum values for TH and TP.
