ABSTRACT:
A data sample recording system having a memory for storing a predetermined number of data samples accumulated over various intervals of time. Each interval of time is divided into a predetermined number of subintervals, there being an electrical circuit for detecting the peak value of data occurring in each of the subintervals. The occurrences of the subintervals are synchronized with a periodic passing of a stylus across a recording medium in a recorder. The predetermined number of data samples is equal to the number of resolution elements of a line of data on the recording medium, stored data being fed out to the recorder in synchronism with the stylus movement to provide a display of data having a predetermined number of resolution elements of display independent of the length of the interval of time.
