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 circuit using h-parameter and r-parameter

the television platform. Batman is a constant name in the DC Comic Universe. And it is only a matter of time until he seeps into the rest of the comics. Whether it is on television‚ in movies or in the comics‚ Supergirl season 2 is paving the way to heroism. There are only a handful of women super heroes out there. But there is one super hero that stands on his own. Batman and Gotham City Batman is one of the darkest superheroes in the DC Comic Universe. He has a dark past that in turn is the reason

I found the connection between dreams and ancient religions to be the most intriguing part of the reading. It certainly does make sense that dreams might have inspired animism and other forms of religion and the way that the ancients interacted with dreams seems to share many similarities with how we interact with dreams. Similar to what happens in a Seneca Dream Guessing ceremony‚ people today analyze their dreams and interpret them in various ways‚ although it is not always in a spiritual light

Fire alarm circuit ABSTRACT Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance will be low and so the voltage across it (below 0.6V). The transistor will be OFF and nothing happens. When there is sufficient

Compare and contrast circuit-switched services‚ dedicated-circuit services‚ and packet-switched services. Circuit switches services uses cloud architecture. This happens when a user leases a connection from a known carrier (which is called a cloud). This works for telephone lines; the user dials the telephone number of the destination computer and establishes a temporary circuit between the two computers. The computer then exchanges various data till the task is finished. When the task is completed

Differentiator and Integrator Circuits Submittal Date: 6/11/2014 Objectives: 1. To demonstrate the operation of a differentiator 2. To demonstrate the operation of an integrator Results: The differentiator circuit caused the cosine wave to output a sine wave and a triangle wave to output a square wave. The Integrator circuit caused the sine wave to become a cosine wave and the square wave into a triangle wave. Conclusions: The differentiator circuit differentiates the wave

As part of the course it was necessary to identify and submit a project using electronic hardware. The nature of this project was to develop‚ build‚ test and present an electronic project that was software controlled by a programmable integrated circuit (PIC). I designed and developed a working system that would automatically cover an outside seating area when rain was detected. I prepared and presented accompanying documentation and presented it to my tutor. I obtained technical information from

the Norton’s theorem. EQUIPMENT Resistor 100Ω‚ 1kΩ and 4.7kΩ‚ digital multimeter(DVM)‚ bread board. INTRODUCTION Some circuits require more than one voltage source. Superposition theorem is a way to determine currents and voltages in a linear circuit that has multiple sources by taking one source at a time. the current in any given branch of a multiple-source linear circuit can be found by determining the currents in that particular branch produced by each source acting alone‚ with all other sources
