Boolean Algebra in Logic Circuits Made Easy
Boolean algebra is a assortment of basic mathematical techniques applied to signify and communicate the logical procedures that happen within a digital circuit. Difference Between Boolean Algebra and Common Algebra Boolean algebra is much like common algebra. The main distinction is that in contrast to common algebra, in which we have parameters that can be […]
Tuned Radio Frequency (TRF) Receiver Circuits
A tuned radio frequency receiver (or TRF receiver) is a form of radio receiver which is made using a number of tuned radio frequency (RF) amplifier stages accompanied by a detector (demodulator) circuit to draw out the audio signal, along with an audio frequency amplifier for amplifying the extracted audio into a loudspeaker. This kind […]
How RCCB Works [with Circuit Diagram]
A Residual Current Circuit Breaker (RCCB) or a ground fault circuit interrupter (GFCI), is a form of circuit breaker which will shut down mains AC power as soon as it detects an discrepancy between the incoming current and the outgoing current, through it. The primary objective of an RCCB device is to cut-off main AC […]
Infrared Car Door Lock Security Circuit
In this post I have explained how to build a simple yet foolproof infrared based remote control, which can be used for locking and unlocking any vehicle door through a personal remote handset. The remote controlled vehicle door lock is foolproof since it works only with a specific IR frequency range, and will not respond […]
12 Basic Digital Logic Circuits Explored
In the following paragraphs I will try to explain the most basic foundations of digital electronic circuits: namely logic gates and logic flip-flops. Whether it is a complex and larger digital circuits, or as simple as a BCD counter, for example the 7490, or a large-scale integration (LSI) microprocessor chip, eventually all of these comprise […]
