Abstract: The main aim of this assignment is to design a pre amplifier circuit with an NPN transistor to be used in a simple public address (PA) system. The pre amplifier is fed from a microphone that produces an average output voltage of 10 mV rms. The amplifier is to operate over a frequency range of 300 Hz to 5 kHz and should have an adjustable volume control. The expected gain of the amplifier is 100. First we are going to design an amplifier for given specifications‚ model the operation of the

demand to analyze the phenomenon and get a better understanding. Moreover‚ from this experiment‚ we can understand the principle of this experiment and learn some circuit knowledge. Background/ Theory In the experiment‚ in an LRC circuit‚ a resistor(R)‚ an inductor (L) and a capacitor (C) are required to connect in series. Just like the figure shows. In the experiment‚ we want to calculate the resonance frequency. We know the current will be maximum when the circuit is driven at its resonance

The output voltage across the resistor (Ry) and capacitor (C) are multiplied using a analog multiplier AD633. According to the port characteristics of AD844‚ Vx=Vy; iy=0; iz=ix; Vw=Vz In figure 4‚ stage 1 is a current to voltage converter‚ by analyzing the circuit‚ Iint=V01(t)Ry (7) The output voltage across the resistor Ry is expressed as V01(t)=RyIin(t)

Investigatory Proposal: Organic Batteries VS Commercial Batteries (7-Rizal Grp.5 2009-2010) I. Introduction A. Background of the Study In the 21st century‚ billions of people rely on electrical energy in one form or another. Today‚ even in some of the most remote regions‚ electricity powers lights‚ radios‚ televisions‚ and many other devices that help people to be more productive‚ comfortable‚ and informed. In some places‚ electricity is generated by hydro-electric dams or coal-fired power

8051 Project: Automatic Lighting and Visitor Counter Andrew Herzog Richard Baker December 13‚ 2007 CMPET 211 Executive Summary The objective of the project was to create a circuit with an 8051 microcontroller that sensed when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was blocked. Discussion To complete the project several smaller circuits were needed to be designed and constructed. The project
