It generally has 4 input lines and 7 output lines. Here we design a simple display decoder circuit using logic gates. Even though commercial BCD to 7 segment decoders are available, designing a ...

Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

In this circuit design tutorial we will use a BC547 NPN transistor and BC557 PNP transistor with a normal push-button to build a soft latching power switch. This soft latch circuit doesn’t require any ...

LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high, sometimes as high as 1000 000 ohms, but when they are ...

This paper analyses some circuits of the analog decoder of (5,2,3) trellis code, which is implemented by CMOS analog circuits. The decoding performance of the analog decoder is given. Simulation ...
