INTRODUCTION The common emitter amplifier circuit makes use of a voltage divider circuit as seen in previous lessons on DC analysis. However‚ for the small signal analysis portion for this circuit‚ the objective is to analyze the input and output signals produced by the amplifier. Because of the resulting output signals‚ which will be discussed further in other sections‚ this amplifier is essential to AC appliances requiring a certain amount of voltage and current gains. II.

experiment. Through experiment Part A: Voltage Divider Rule we has use the TINA software to create a series connection as shown in Figure 5.1 to determine the whether the divider rule is correct or not by using theorical method. We set the power of generator to 9V and put 3 resistors in the circuit and label it as R1‚ R2 and R3‚ each with the resistance of 1k‚ 3.3k and 4.7k. We also added a voltmeter reading between each of the part of resistor to take the voltage reading. After all components in the

Overview of the project: Circuit description TEXAS INSTRUMENTS MSP430G2231 is the heart and brain of this circuit .the internal adc of the mcu with a resistor network voltage divider is used to measure the input voltage. Then 3 digest of comm anode 7 segment display is used to display final converted voltage. As you can see in the schematic the displays are multiplexed with each other. means we switch on one display and put the corresponding digit on this while other two displays are

This block contains the LM35 sensor. It receives 9V supply from a battery and delivers an output voltage signal that ranges between 0 and 500 mV depending on temperature‚ 0V at 0ºC and 500mV at 50ºC increasing linearly in between. It may deliver more than 500 mV when the temperature is higher than 50ºC ‚ but it is useless since the conditioning system has a ceiling temperature of 50ºC beyond which sticks displaying as if it was 50ºC. It has a RC damper of 1uA capacitance and 100Ω resistor connected

LCD is used to display the measured voltage. The PIC microconotroller used in this project is PIC16F688 that has 12 I/O pins out of which 8 can serve as analog input channels for the in-built 10-bit ADC. The voltage to be measured is fed to one of the 8 analog channels. The reference voltage for AD conversion is chosen to be the supply voltage Vdd (+5 V). A resistor divider network is used at the input end to map the range of input voltage to the ADC input voltage range (0-5 V). The technique is demonstrated
