Power Supply Basics - Learn About Electronics
WEBIf you are considering building or repairing a power supply, especially one that is powered from mains (line) voltages the power supply modules on this site will help you understand how many commonly encountered circuits work.
Registers - Learn About Electronics
WEBAn electronic register is a form of memory that uses a series of flip-flops to store the individual bits of a binary word, such as a byte (8 bits) of data. The length of the stored binary word depends on the number of flip-flops that make up the register.
2.0 Digital Logic - Learn About Electronics
WEBThis module introduces the basics of digital logic and shows how the whole of digital electronics depends on just seven types of logic gates, connected together with a minimum of additional components.
Amplifiers - Learn About Electronics
WEBAn amplifier is used to increase the amplitude of a signal waveform, without changing other parameters of the waveform such as frequency or wave shape. They are one of the most commonly used circuits in electronics and perform a variety of functions in a great many electronic systems.
Digital Counters - Learn About Electronics
WEBSynchronous BCD Up Counter. A typical use of the CLR inputs is illustrated in the BCD Up Counter in Fig 5.6.11. The counter outputs Q 1 and Q 3 are connected to the inputs of a NAND gate, the output of which is taken to the CLR inputs of all four flip-flops.
Buck Converters - Learn About Electronics
WEBThe buck converter is a form of DC to DC converter that can take an input directly from a DC source, such as a battery. The input could also be DC derived from the AC mains (line) as shown in Fig. 3.1.1 via a rectifier/reservoir capacitor circuit. The AC input to the rectifier circuit could be AC at high voltage directly from the AC mains ...
Circuits and Resistors - Learn About Electronics
WEBLater modules in this series will introduce resistors, both as single components and as part of more complex networks. Conductors and insulators. Materials are used in electrical circuits. Resitors, resistivity and the effects of temperature on resistance.
Boolean Algebra - Learn About Electronics
WEBThe laws of Boolean algebra are similar in some ways to those of standard algebra, but in some cases Boolean laws are unique. This is because when logic is applied to digital circuits, any variable such as A can only have two values 1 or 0, whereas in standard algebra A can have many values.
