Title: Method and apparatus for detecting main peaks in an electrical signal
IPC: G01R19/04
Filed: 1973-09-12
Abstract: 1424387 Detecting peak voltages TELEPLAN AB 12 Sept 1973 [15 Sept 1972] 42946/73 Heading G1U The timings of peaks in an electrical signal are determined by comparing the signal with a reference level function which is variable to take account of the signal amplitude, the signal itself being delayed for a time equal to that necessary to generate the reference function. The reference function is generated by determining for each of a number of successive time intervals, the maximum value of the signal amplitude in the three preceding intervals. In Fig. 2 this maximum value for each interval is plotted as 9. The variable reference function 11 is set half-way between the maximum value and a minimum reference level 10. Any signal crossing the reference function 11 is defined as a peak and its timing determined. Since the reference function takes a finite time to construct, the signal being examined must be delayed by 1¢ intervals before comparison. The method is stated to be applicable to determining bearings of radar echoes from a rotating directional antenna. Apparatus for determining the maximum values is shown in Fig. 3 and comprises four sections 161-164 which are enabled sequentially one, for each interval, by the turning on of FET's 23. Capacitors 19 thus are charged to the maximum level attained during the associated time period or the immediately adjacent intervals via diodes 20, 21, 22. At the end of each time period, the voltage on the capacitor 19 associated with the immediately preceding time interval is transferred to output capacitor 18 by the turning on of gates 24 and 17. Gate 15 is then turned on to erase the voltage on the capacitor 19.
