Due to the timing differences for the rising and the falling edge there will be a slight difference between the length
of the input pulse and the length of the output pulse. It can be calculated using the following formulas:
• Δt_HS = (t_dr(HS) + 0.2 t_r(HS)) - (t_df(HS) + 0.8 t_f(HS))
• Δt_LS = (t_df(LS) + 0.2 t_f(LS)) - (t_dr(LS) + 0.8 t_r(LS)).
