Introduction

As opposed to continuous time capacitor circuits in analog signal processing, Switched Capacitor (SC) circuits find wide range of applications in discrete time signal processing. These circuits function by charging and discharging capacitors with the help of switches to provide flow of charge in desired direction. SC filters are embedded in integrated circuits due to their inherent temperature and voltage characteristics.

A typical SC circuit is equivalent to a discrete time resistance. Consider a simple example of a SC circuit:

Clock pulses are applied on switches to perform transition between two voltage sources shown in the figure. It is made sure that the clock pulses don’t overlap so that the voltage sources are not short circuited. It Continue reading...

Analog and digital signals, basically, differ in their graphs of voltage versus time. Analog signals have a continuous signal function with respect to time (Angoletta, 2014). The signal here can be sound, light, temperature, pressure, etc. The signals have smooth continuous changes similar to an analog watch. On the other hand, digital signals have a discrete (taking only binary values 0 and 1) function with respect to time. The signals have determined levels such as the case of the digital clock where time can only take account of 0 to 9.
The advantages of using analog versus digital signals Continue reading...

An alarm clock is a timepiece manufactured to include a device that can be set in advance to sound a ringer or buzzer, in order to wakethe user at the preset time. An analog clock displays the time by the position of the clock “hands” on a dial. (Compare with a digital clock which the displays time using a series of digits representing hours, minutes and (optionally) seconds).

Characteristics of the Analog Alarm Clock

A traditional analog alarm clock – as described here and shown in Figure 1 – is powered by clockwork, using springs to store energy in a mechanism to drive the clock and the Continue reading...

The calculated Hex values for the various voltages are calculated below;

0.5V = 0.5/(5/255)
= 25.5 ~ 26
= 1A Hex code
1.5V = 1.5V/(5V/255)
= 76.5 ~ 77
= 4D Hex code
2.5V = 2.5V/(5V/255)
= 127.5 ~ 126
= 7E Hex code
3.5V = 3.5V/(5V/255)
= 178.5 ~ 179
= B3 Hex code
4.5V = 4.5V/(5V/255)
= 229.5 ~ 230
= E6 Hex code
1.2 The measured values for the various voltages are shown below;
0.5V = 19
1.5V = 4C
2.5V = 7F
3.5V = B3
4.5V = E6
The calculated values are higher than the measured values; this is mainly due to the rounding off so as to get a whole number during the calculation of the hex code value. The difference is due to this. Continue reading...

Introduction
It is a part of the job of an energy manager that he minimizes the energy loss of the building by controlling the ambient temperature of the building or different parts of the building. In order to maintain the temperature and save valuable energy, a data acquisition and monitoring system is needed that will display the ambient temperature with the help of sensors. This supervisory control system will be designed to control the remote infrastructure that handles the heating system. The energy manager will be in control of this system. First the data of the room will be Continue reading...

Significant tech differences between ADSL and Recommended Alternative

Using ASDL phones is not suitable as the only communications at a hospital because the staff in out of the hospital need be able to communicate reliably with mobiles. ASDL connects to the Internet using existing copper telephone lines known as Plain Old Telephone Services (POTS). VoIP can support smart phones, pager messaging and other mobile devices and with the correct interfacing analog phones can be supported by VoIP (Shepler 2005). A gateway is needed for the interface so different networks can be connected. The secret is the RJ-11 or similar socket on Analog Continue reading...

System Circuit Analysis and Design an Integrated Operation Amplifier

Introduction
The amazing device called operational amplifier (op-amp) is a solid state IC which has the abilities to use external feedback to control its operations. As one of the most versatile device in the state-of-art solid state electronics technology till date, op-amp has been used with several different and remarkable functions. Apart from its use as a high gain amplifier, it has been typically used to device analog computers, various amplification requirements where high gain is required, cmos, short circuit protection, low input current frequency compensation and a myriad of different functionalities.
Equally interesting has been the evolution of Continue reading...

The type of hardware used in a glucometer.

A glucometer (glucose meter) is a medical technology device used measure glucose concentration in a given solution. The units of measurement used vary by region and they are milligram per deciliter (mg/dl) and millimole per liter (mmol/L). Glucometers are critical elements in Home Blood Glucose Monitoring (HBGM) devices used by diabetics who suffer from Type 1 and Type 2 Diabetes Mellitus. HBGM devices are used to monitor blood sugar levels on a daily basis with multiple measurements taken in a single day (Dalvi).
The glucometer hardware described in this paper is based on designs by Freescale Semiconductor Company. The Continue reading...
