CHAPTER 9
Oscillators
To generate an alternating-current (AC) signal, usually we start with an oscillator circuit. Depending on the circuit, oscillators generally provide sine-wave signals or pulsed waveforms. Other types of waveforms can be generated, such as triangle waves, which are generally derived from a square-wave generator circuit (e.g., an “on/off” circuit). This chapter will introduce the reader to some types of oscillators. There are a multitude of oscillator circuits, and some other types will be shown in subsequent chapters.
Therefore, we will explore how oscillation occurs and examine different types of oscillators used in audio ...
