What wave form would appear on the voltage outputs at the collectors of an astable, multivibrator, common-emitter stage?

🔍 Key Concepts

• Astable multivibrator operation (it has no stable state and continuously switches between two states) • The typical waveform at the collector of a common-emitter switching transistor (what does saturation / cutoff look like over time?) • Difference between sine, sawtooth, square, and half‑wave waveforms in basic electronics

💭 Think About

• Picture how each transistor in a common-emitter astable multivibrator behaves over time: is it acting like a linear amplifier or like an ON/OFF switch? • If the transistor is either saturated (fully on) or in cutoff (fully off), what does the voltage at its collector look like versus time? • Compare that expected shape to the definitions of sine, sawtooth, square, and half-wave waveforms.

✅ Before You Answer

• Verify how the collector voltage changes when a common-emitter transistor switches between saturation and cutoff. • Check which of the four options represents a waveform with two distinct, nearly constant levels and relatively fast transitions between them. • Confirm that an astable multivibrator is a relaxation oscillator, not a linear sine-wave oscillator.
