A peak detector for electrical signal peaks including a capacitor which is charged, via a rectifying element, to a voltage corresponding to the peak value. At the end of the peak a discharging element connected parallel to the capacitor is activated for a predetermined period of time, with the result that the capacitor is discharged over a fixed fraction of its peak voltage. At the end of the predetermined period of time, the discharging element is reactivated, with the result that a substantially constant voltage remains as a reference level.
