The development of a fifty kilocycle per second triangular wave generator is discussed. Some of the possible applications for such a device are considered, as are a number of different methods for accomplishing the desired result. Three of these methods are considered in some detail, and the passive RLC integrator circuit proves to be the best of those investigated. A circuit for a self-contained fifty kilocycle per second triangular wave generator employing semiconductor active elements throughout is given. A mathematical analysis of the idealized RLC integrator circuit is provided. Numerical calculations based on this analysis are compared with values obtained from measurements on the actual circuit, A special linearity test is described, and measurements obtained from this test are compared with the calculated linearity based on ideal conditions. The results of the tests on the subject circuit showed that it will generate a fifty kilocycle per second triangular wave of plus or minus one percent linearity, 0.1 percent amplitude stability, and peak-to-peak output voltage of about thirteen volts.
