Objectives of this experiment:
This circuit generates a symmetrical triangle waveform, since its main timing capacitor charges in both positive and negative direction via the same resistance network, The frequency and amplitude can be varied by 100K and 10K potentiometer. The frequency of the triangle wave is varied from 800 Hz-8KHz.

Built in regulated Power supply: +9V/300mA; -9V/300mA
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
