3-1 CHAPTER 3 WAVEFORMS AND WAVE GENERATORS LEARNING OBJECTIVES Upon completion of this chapter you will be able to: 1.    Explain the operation of a stable, monostable, and bistable multivibrators. 2.    Explain the operation of a blocking oscillator. 3.    Explain the operation of a sawtooth generator. 4.    Explain the operation of a trapezoidal wave generator. 5.    Explain how the jump voltage is produced in a trapezoidal wave generator. WAVEFORMS This chapter will present methods of generating waveforms. Before you begin to study how waveforms are generated, you need to know the basic characteristics of waveforms. This section will discuss basic periodic waveforms. PERIODIC WAVEFORMS A waveform which undergoes a pattern of changes, returns to its original pattern, and repeats the same pattern of changes is called a PERIODIC waveform. Periodic waveforms are nonsinusoidal except for the sine wave. Periodic waveforms which will be discussed are the sine wave, square wave, rectangular wave, sawtooth wave, trapezoidal wave, and trigger pulses. Sine Wave Each completed pattern of a periodic waveform is called a CYCLE, as shown by the SINE WAVE in figure 3-1, view (A). Sine waves were presented in NEETS, Module 2, Alternating Current and Transformers, Chapter 1.
