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

Object counter using 8051 microcontroller.
This article is about a simple object counter/visitor counter using 8051 microcontroller . AT89S51 belonging to the 8051 family is the microcontroller used here. This circuit can count the number of objects passing across a line , number of persons passing through a gate/door and so on. The can be simply divided into two sections i.e. the sensor section and the display section.

Sensor.

The sensor part consists of a ultra bright led (with focus), and LDR, opamp LM324 and the associated passive co ....etc

advantages:
Enabling women by placing them in typically male industries usually means an increase in security. FMC mines love to employ women in their mines because although women will have to work slower due to physical limitations, this allows for a general increase in safety; Fewer injuries on site and, of course, fewer deaths. In the direction, the woman asks more questions, is generally less competitive, and will admit more willingly when she does not understand something. Men are not smarter than women; Women are more vocal ....etc

Phishing is the attempt to obtain sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money), often for malicious reasons, by masquerading as a trustworthy entity in an electronic communication. The word is a neologism created as a homophone of fishing due to the similarity of using a bait in an attempt to catch a victim. Communications purporting to be from popular social web sites, auction sites, banks, online payment processors or IT administrators are commonly used to lure unsuspecting vi ....etc

hydraulic intensifier is a hydraulic machine to transform hydraulic energy at low pressure in a volume reduced to a higher pressure

Such a machine can be built by mechanically linking the two pistons, each working in a cylinder separated with a different diameter. As the pistons are mechanically connected, their strength and their stroke length are the same. If the diameters are different, the hydraulic pressure in each cylinder varies in the same ratio as their areas: the small piston giving birth at a pressure more high. When the pressure ....etc

digital clock using 8051 advantages and disadvantages

Digital clock displays the time using numbers. This circuit is used in many applications like cars, railway stations, houses, offices, etc. in order to provide accurate time and date. In this type of applications, normally we use RTC (Real Time Clock) ICs to display the time and date accurately. This circuit displays the time on LCD. For this clock, we can set the time at any instant. Here the clock works in 24 hour mode and the RTC chip is configured by programming 8051 controller.
