Differential pulse-code modulation

INTRODUCTION

Differential pulse-code modulation (DPCM) is a signal encoder that uses the baseline of pulse-code modulation (PCM) but adds some functionalities based on the prediction of the samples of the signal. The input can be an analog signal or a digital signal.

If the input is a continuous-time analog signal, it needs to be sampled first so that a discrete-time signal is the input to the DPCM encoder.

Option 1: take the values of two consecutive samp ....etc

Electric Bell
Coffee call there is a mechanical Bell that operates by means of an electromagnet. When an electric current passes, this produces a repeated buzzing sound or l zga ij. Electric calls are widely used at railway crossings, in phones, fire alarm and security systems, and school bells, door bells, and anxiety in industrial enterprises, but now they are commonly replaced with electronic echo.
Types Of
shortstop Bell
As the circuit breaker type electric Bell works.
The most widely used form is the shortstop Bell, which produces a cont ....etc

Folded Plate Structure

a thin-walled building structure of the shell type. Folded plate structures consist of flat components, or plates, that are interconnected at some dihedral angle. Structures composed of rectangular plates aresaid to be prismatic. In modern construction practice the most widely used folded plate structures aremade of cast-in-situ or precast reinforced concrete (including prestressed and reinforced-cementstructures). The structures are used as roofs for industrial and public buildings.The main advantage of folded plate st ....etc

advantages and disadvantages of digital tachometer pdf

Tachometer (Revolution counter, tachometer, tachometer, the RPM gauge) is an instrument for measuring the rotational speed of the disk or, as in the machine.The engine or other device usually displays the number of revolutions per minute (RPM) on the calibrated analog dial, but digital displays are becoming more common. The word comes from the Greek (Tachos speed) and Metron ( measure). In fact the word tachometer and speedometer are of equal importance: a device that measures the spe ....etc

pdf on advantages and disadvantages of hovercraft

Hovercraft operate on a cushion of air and during their earlier years were considered to fly above the surface below. They generate a volume of lift air, maintained by a flexible skirt at a higher pressure than the atmospheric pressure above. Their weight is therefore balanced by the lift that is generated.

Our hovercraft use commercially available technology, are diesel powered, and use aluminium as the primary hull structure to make them easy to maintain and repair in the field.

There ar ....etc

A beverage can is a metal container designed to hold a
fixed portion of liquid such as a carbonated soft drinks,
alcoholic beverages, fruit juices, teas, herbal teas, energy
drinks, etc. Beverage cans are made of aluminium (75% of
worldwide production) or tin-plated steel (25% worldwide
production). Since we use aluminium so frequently (75% of
worldwide production) it is important to recycle
aluminium. Recycling aluminium not only helps to keep
the landfills clear but it also saves energy. Recycling 40
aluminium beverage cans saves the ....etc
