Antenna: we are going to design a Simple Doorbell circuit using a 555 Timer IC. It is a very common and useful device. Almost everyone uses it. FM transmitter is a low-power FM radio transmitter that communicates Read more Read more.
How the FM Transmitter Works. The circuit is powered by a 9V power supply.Transistor Q1 is a high gain audio amplifier that amplifies the sound detected by the electret microphone.The output of Q1 is fed into the frequency modulating circuit created by transistor Q2, inductor L1, and variable capacitor C5.. This is a very high frequency (VHF) circuit, so you will want to use transistors with a
Make Your Own Low-Power AM Radio Transmitter Circuit Diagram
Although the circuits used in radio stations for AM broadcasting are far more complicated, this nevertheless gives a basic idea of the concept behind a broadcast transmitter. Plus it is a lot of fun when you actually have it working! Before we get into the step-by-step instructions for building the circuit, we'll first go over the circuit design.
Building AM and FM radio receivers and transmitters is a fun way to explore concepts like electromagnetic waves, resonance, filters, and audio amplification. The projects can be used in a home audio system or made portable with battery power.
AM and FM Radios Circuit Diagram
A FM transmitter is a device that uses the principles of frequency modulation to broadcast sound supplied at its input. Typical FM transmitter design's usually follow the block diagram below; The signal strength of audio inputs into the transmitter is usually low therefore an amplifier is usually built to bring the signal level up.
