Labels and Jumps
Labels Labels are names which are used to identify various pieces of code. In effect they give a name to a particular location in an...
The MOV and INT Instructions
The MOV Instruction The MOV instruction is the instruction which will appear more than any other in an assembler program. All that is does is...
The 8086 Chip
Before beginning to write programs in assembler, you need to know a few things about the chip for which you are writing the program. This...
Working with MosFet’s
The Metal-Oxide-Semiconductor Field-Effect Transistor, or MOSFET for short, is similar in many ways to the junction FET (JFET). Both are voltage-driven unipolar devices that depend...
Field Effect Transistors
Field Effect Transistors (FET’s): Field Effect Transistors (FET’s) are unipolar rather than bipolar devices, and this gives them certain properties that are superior to those...
Transistor Amplifier Design
We were having trouble finding an exact replacement transistor while repairing a piece of equipment. Figuring that an exact replacement was going to be impossible...
Oscillators and Multivibrators
Oscillators based on the bipolar junction transistor (BJT) are the subjects of this article. Previous articles in this series have included articles on the characteristics...
Practical Transistor Circuits
More Power Amplifiers: Today the easiest way to build a low- to medium-power audio amplifier is to pick an integrated circuit (IC) amplifier from a...
Audio Amplifier Basics
Transistors are the key components in many different kinds of audio preamplifiers, amplifiers, and tone-control circuits. Recent articles in this series have discussed the operation...
Power Amplifier
An audio power amplifier can boost weak signals from a tuner, CD player, or tape deck to fill a room with sound. This article focuses...

Resistors
What do resistors do? Resistors limit current. In a typical application, a resistor is connected in series with an LED: Enough current flows to make...
Voltage Rating of a Capacitor
All capacitors have a maximum voltage rating and when selecting a capacitor consideration must be given to the amount of voltage to be applied across...
