Schematic design of Signal generator
Notes:
Here is a simple triangle/squarewave generator using a common 1458 dual op-amp that can be used from very low frequencies to about 10 Khz. The time interval for one half cycle is about R*C and the outputs will supply about 10 milliamps of current. Triangle amplitude can be altered by adjusting the 47K Ω resistor, and waveform offset can be removed by adding a capacitor in series with the output.
