Square Wave Oscillator with Frequency Adjustment

Square Wave Oscillator with Frequency Adjustment

It is a quad wave generator with frequency and voltage level adjustment. It uses an astable multivibrator with LM 555 and which maintains symmetry in the positive and negative ranges. The power is supplied by a symmetrical source using the LM 7809 and LM 7909 regulators.
Simple and practical circuit for everyone working on an electronic bench. Continuar lendo Square Wave Oscillator with Frequency Adjustment
