transmitted power (sidebands)? 5. The antenna current of an AM transmitter is 12 A when unmodulated but increases to 13 A when modulated. Calculate the percent modulation. 6. An intelligence signal is amplified by a 70% efficient amplifier before being combined with a 10 kW carrier to generate the AM signal. If it is desired to operste at 100% modulation‚ what is the input power to the final intelligence amplifier? 7. A transmitter with a 10 kW carrier transmits 11.2 kW when modulated with a

CHAPTER THREE ANALYSIS AND DESIGN 3.1 INTRODUCTION This chapter deals with the process of obtaining the design specifications of the wireless Frequency Modulated Transmitter with a frequency of 100MHz in a range of 100m under accurate conditions. From the block diagram shown in FIG. 2.1‚ various circuit components are now chosen and appropriate approximate values are now chosen to match its properties as well as perform duties of the stages. The entire system could be grouped into two major stages

Neuro- is nerves and transmitter can send waves that carry a signal. In other words‚ a neurotransmitter is sort of like a mail man‚ although in this case instead of being called a mail man‚ it is called a chemical messenger. Like a mail man‚ a chemical messenger can transmit signals or codes from one neuron to another. And the way that this takes place is by synapses. There are two synapses that have two different names that are allowing these neurons to communicate or send messages to one another

Power‚ a word that‚ said alone‚ has a plethora of definitions in which the word could be solely interpreted. Over the course of known history‚ humans have always had problems with self control. In result‚ the lust for power is one that is seen widely in both fiction and in history. Though most would deny it‚ many people wish to say that they have more than their counterparts. This is because humans have a natural craving for power and control. The drive for power throughout human history has been

I ’ve chosen to explore the topic money and power. The type of power here is economic power. This type of power is being used every day in our lives‚ when we use money to buys things‚ when we give money to people in exchange for goods or services. An example of this is when someone hires a maid‚ she is being paid money to clean a house‚ and the employer has power over her‚ they can tell her what to clean and how to clean it. The real power that money gives us is the power to choose. We can choose

DC Circuits: Electric Power PHY 114 Lab Report 10/09/2013 Abstract: The purpose of this experiment was to look at electric power dissipated in a load resistor in a circuit with a real power source‚ which has a finite internal resistance. We discover a surprising result about how to deliver the most power to a device from a source. Consider a simple circuit in which a battery of voltage drives a current through a resistor of resistance. As we have seen‚ the battery is continuously doing

The power of persuasion Throughout time art has played a major role. Many people over time have used self image to control and persuade people to be on their side. This technic of using image to control and persuade people was first used by the warrior of stonehenge. During this time most people wore sheep skin‚ the warrior of stonehenge gain control of people by wearing expensive jewelry and nice cloth. One piece of jewelry that he wore were two gold hair pieces. These hair pieces were told
