Maximum is simply the maximum value of all the samples within the range specified.
Minimum is the minimum value of all the samples within the range specified.
Peak to Peak is calculated by taking the difference between the minimum value and the
maximum value within the sample range specified.
Value is calculated by finding the mid-level crossings, and estimating the time between
crossings. A hysteresis approach is taken to finding the mid-level crossing point to avoid
the effects of overshoot and ringing.
For the highest amplitude component chosen is displayed from a Fourier transform of the
signal.
For the highest amplitude component chosen is displayed from a Fourier transform of the
signal.
For the highest amplitude component chosen is displayed from a Fourier transform of the
signal.
Calculated by taking the time at which three consecutive mid-level crossings occur. The
Duty Cycle is percentage ratio of the time from the first rising mid-level crossing to the
next falling mid-level crossing divided by the time from the first rising mid-level crossing
to the next rising mid-level crossing.
Note Cleverscope assumes that the signal is repetitive.

A hysteresis approach is taken to finding the mid-level crossing point to avoid the effects
of overshoot and ringing.
For the highest amplitude component chosen is displayed from a Fourier transform of the
signal.
Cleverscope assumes that the signal is repetitive. The pulse length is calculated by finding
the mid-level crossings and calculating the time difference between the positive going
crossing and the next negative going crossing.
Cleverscope assumes that the signal is repetitive. The duty cycle is calculated by taking
the time at which three consecutive mid-level crossings occur. The duty cycle is
percentage ratio of the time from the first rising mid-level crossing to the next falling mid-
level crossing divided by the time from the first rising mid-level crossing to the next rising
mid-level crossing
