This presentation discusses pulse generators. It begins with an introduction that defines pulses and describes different types of waves including square waves. It then explains the circuitry of an astable multivibrator and how it can be used to generate pulses. Characteristics of pulse generators like rise time, width and repetition rate are covered. Applications include driving devices and digital communication. Advantages include simple control systems and flexibility of time parameters, while disadvantages include amplitude drop during pulses. The presentation concludes with a summary of the content.
