LASER TORCH BASED VOICE TRANSMITTER AND RECEIVER
Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit (Fig. 1) comprises c ....etc

The superheterodyne radio receiver, or last name, first name, to give it a super heterodyne receiver, STI is one of the most popular forms of the receiver is used today in various applications of radio receivers passed for bilateral communication lines, as well as many mobile radio communication systems.

Although other forms of radio receiver is used, the receiver supergeterodinnogo is one of the most commonly used forms. Although Initially developed in the early days of radio or wireless technology, at supergeterodinnogo supergeterodinnoj or ....etc

Abstract:

The survival triplet today for any company is how to manage its product /service Cost, quality, and performance. The customers are continuously demanding high quality and better performance products/services and at the same time, they want the prices to fall. The shareholders are also demanding a required rate of return on their investment with the company. Thus, cost has become a residual. The challenge is being able to manufacture or provide service within the stipulated cost framework. Thus, cost management has to be an ongoing c ....etc

Having looked at the concepts behind the superheterodyne receiver it is helpful to look at a block diagram of a basic superhet. The superheterodyne block diagram is relatively straightforward and builds on the basic functional block used to convert the incoming frequency down to a fixed intermediate frequency stage.

While there may be some simplified versions for a superheterodyne block diagram, each receiver will be different as a result of the differing requirements for each receiver. However the basic principles are the same, and many super ....etc

Superheterodyne is a contraction of supersonic heterodyne, where supersonic indicates frequencies above the range of human hearing. The word heterodyne is derived from the Greek roots hetero- different, and -dyne power. In radio applications the term derives from the heterodyne detector pioneered by Canadian inventor Reginald Fessenden in 1905, describing his proposed method of producing an audible signal from the Morse code transmissions of the new continuous wave transmitters. ....etc

cost sheet and estimated cost sheet of amul company

The Birth of Amul

It all began when milk became a symbol of protest
Founded in 1946 to stop the exploitation by middlemen
Inspired by the freedom movement
The seeds of this unusual saga were sown more than 65 years back in Anand, a small town in the state of Gujarat in western India. The exploitative trade practices followed by the local trade cartel triggered off the cooperative movement. Angered by unfair and manipulative practices followed by the trade, the farmers of the district approac ....etc
