ABSTRACT

The basic policy for component selection is that followed throughout this book-to use as few capacitor values as possible, which means sticking to the sparse E3 or E6 series, and let the resistor values come out as they may. I decided that no more than two resistors from the E24 series would be used in series or parallel to get as close as possible to the desired value. Where it could be done the resistors would be of near-equal value to get the best possible improvement in accuracy by using multiple resistors, as explained in Chapter 12. An error window for the nominal value (excluding tolerances) is set at ±0.5%. 1% tolerance resistors are assumed.
