Square Waves Produced with a Multivibrator

Author: J.B. Hoag

The multivibrator circuit, as is well known, develops an irregular wave-form which is rich in harmonics. With proper C-bias on the tubes, the output can be made to approximate a square wave-form. A circuit for this purpose is shown at the left in Fig. 30 I, and is discussed in Sec. 30.8.
