Practical Oscillator Design
26 This section briefly covers some practical problems with oscillators.
Before you proceed, review the important points of this chapter by answering the following questions.
The main practical problem with building oscillators is selecting the coil. For mass production, a manufacturer can specify and purchase the exact coil required. But in a lab or workshop (where you are building only a single circuit), it is often difficult or impossible to find the exact inductor specified in a circuit design. What usually happens is that you use the most readily available coil, and design the rest of the circuit around it. This presents three possible problems:
- You may not know the exact value of the inductance.
- The inductance value may ...
