Automatic Plotting of Cartridge Response
Journal of the Audio Engineering Society · Volume 7 · Issue 3 · pp. 135–140 · July 1959
Abstract
A system for the automatic plotting of frequency response of phonograph cartridges is presented. The major parts of the system are a piezoelectric ceramic driver, an RIAA compensating network, and graphic recording equipment. The driver consists of a stack of modified Lead Zirconate Titanate (PZT) length expanders acting together as a bar. The graphic recording equipment includes a Bruel & Kjaer (B & K) Signal Generator in conjunction with a B & K High Speed Level Recorder. A description of these components is given and typical response curves are shown. The latter are compared with curves obtained in the usual manner.
