2. Introduction
The FM transmitter has 3 stages, A (VFO) Variable frequency Oscillator (30 mw), a class C driver stage (150 mw) and a class C final power amplifier (1 Watt).
Basically every FM Transmitter has to have a Voltage Controlled Oscillator (VCO). This is a high frequency oscillator whose output frequency changes based on the voltage applied at a particular control point. This is a variable frequency oscillator (VFO).

3. EMBEDDED SYSTEMS Definition for :- EMBEDDED SYSTEMS
A combination of hardware and software which together
form a component of a larger machine.
An example of an embedded system is a microprocessor that
controls an automobile engine.
An embedded system is designed to run on its own without
human intervention, and may be required to respond to
events in real time.

7. BATTERY
An electrical battery is a combination of one or more electrochemical cells, used to convert stored chemical energy into electrical energy.
The battery has become a common power source for many household, robotics and industrial applications.
Larger batteries provide standby power for telephone exchanges or computer data centers

8. TRANSISTOR
The BC547 transistor is an NPN Epitaxial Silicon Transistor.
It is used in general-purpose switching and amplification BC847/BC547 series 45 V, 100 mA NPN general-purpose transistors.
The transistor is a "CURRENT" operated device and that a large current (Ic) flows freely through the device between the collector and the emitter terminals.

9. BC548 The BC548transistor is an NPN Epitaxial Silicon Transistor.
The BC548transistor is a general-purpose transistor in small plastic packages.
It is used in general-purpose switching and amplification BC848/BC548 series 45 V, 100 mA NPN general-purpose transistors.
Whenever base is high, then current starts flowing through base and emitter and after that only current will pass from collector to emitter

12. Resistor
Resistor is a two terminal passive electrical component that implements electrical resistance as a circuit element.
Resistors limits or regulate the flow of electrical current in an electronic circuit.
Resistors are available in a range of different resistance values which are used as per the requirement.

13. Capacitor
capacitor is a two terminal passive electrical component used to store the electrical energy electrostatically in an electrical field
Capacitors are two types electrolytic and ceramic.
Ceramic capacitors are unpolarized. These capacitors have negligible internal inductance or resistance.
Electrolytic capacitors are polarized and if connected backwards are likely to explode.
