Automatic Plotting of Cartridge Response
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.
