ETB-139 – Study of Blocking Oscillator with Power Supply is an educational training kit designed to demonstrate the working principle and waveform behavior of a blocking oscillator—a simple yet important pulse-generating circuit used in timing, switching, and waveform generation applications. This trainer enables students to analyze the operation of both monostable and astable blocking oscillators, observe waveform shapes using an oscilloscope, and understand the influence of transformer action, feedback, and timing components on pulse generation. With a built-in regulated power supply and accessible test points, the model provides a hands-on learning experience in pulse and switching electronics. Key Features:
