The basic full wave rectifier circuit can be seen to use two diodes and a centre tapped transformer. This circuit is very easy to implement, although it does need a centre tapped transformer. There are only two electronic components, i.e. the diodes and these are easily wired up.

8085A, 8085AH, and M8085AH are the three variants of 8085. The major difference between them is their operating clock speed of 3, 5, and 6 MHz respectively. 8085 is fabricated using NMOS technology and contains seven general purpose registers along with a few special purpose registers. The processor chip 8085A has 40 pins.

CRO is an acronym used by marketers as a catch all to describe the process for increasing the number of conversions a website gets. But CRO meaning is often misunderstood. CRO stands for conversion rate optimisation or just conversion optimisation. The heart of a CRO is Cathode ray tube.

This bypass capacitor causes the frequency response of the amplifier to break at a designated cut-off frequency, ?, by-passing (hence its name) signal currents to ground. The function of the emitter filter bypass capacitor in a CE amplifier is to provide a low resistance path for ac signals.

A phototransistor is a device that converts light energy into electric energy. … Photons (light particles) activate phototransistors and are used in virtually all electronic devices that depend on light in some way.

The actual operation of a phototransistor depends on the biasing arrangement and light frequency. … On the other hand, if the same junction is reverse biased, the increase in current flow will be considerable and is a function of the light intensity. Therefore, reverse bias is the normal mode of operation.

Satellite that appears to be located at a fixed point in space when viewed from the earth’s surface. Satellites located in geosynchronous orbit move in time with the rotation of the earth. Geostationary satellites are located 22,237 miles (36000 kms) above the earth’s surface.

A SCR (thyristor) consists of four layers of alternate P- type and N- type (P-N-P-N) silicon semiconductors layers, forming three junctions J1, J2, and J3, (J1 and J3 operate in forward direction while middle J2 operates in reverse direction) and three terminals known as Anode (A), Cathode (K), and Gate (G).

A logic circuit that has a high output only when all its inputs are low is NOR gate. A NOR gate is a logic gate which gives a positive output only when both inputs are negative. Like NAND gates, NOR gates are so-called “universal gates” that can be combined to form any other kind of logic gate.
