CHAPTER 14

Blocking Oscillators

LEARNING OBJECTIVES

After reading this chapter, you will be able to:

  • Understand the principle of operation of regenerative circuits called blocking oscillators
  • Describe monostable blocking oscillators with base timing and emitter timing and derive the expressions for their pulse width
  • Describe RC-controlled and diode-controlled astable blocking oscillators and derive the expressions for the frequency of oscillations
  • Realize the influence of core saturation on the pulse width of the blocking oscillator
