Today , in this content, how to make FM radio receiver ? Tell about you.
An electronic device called a radio or FM receiver picks up radio waves and transforms the information they carry into usable forms. To capture the desired frequency waves, an antenna is used. The receiver first employs electronic filters to separate the intended signal from all other signals captured by the antenna, then an electronic amplifier to boost the signal's power for additional processing, and finally demodulation to extract the desired information.
An instruction manual for building an FM radio receiver
circuit is provided below:
assemble the necessary elements:
IC for FM radio receiver (such as the TEA5767)
Capacitors (0.1 uF and 100 uF) (0.1 uF and 100 uF)
Resistors (10 kohm and 220 ohm) (10 kohm and 220 ohm)
Inductors (10 uH and 100 uH) (10 uH and 100 uH)
antenna cable
Circuit board or a breadboard
leapfrog wires
power supply (such as a 9V battery)
Adhere the TEA5767 IC to the breadboard or circuit board in
accordance with the datasheet's specified pinout diagram.
The 0.1 uF capacitor should be connected to the IC's pins 1
(VC) and 2 (GND).
Between the IC's pins 2 (GND) and 3 (VCC), connect the 100 uF
capacitor.
Between the IC's pins 3 (VCC) and 6 (SDIO), connect the 10
kohm resistor.
Between the IC's pins 6 (SDIO) and 8 (SCLK), connect the 220
ohm resistor.
Between the IC's pins 6 (SDIO) and 7 (SEL), attach the 10 uH
inductor.
Between the IC's pins 7 (SEL) and 8 (SCLK), connect a 100 uH
inductor.
Attach the antenna wire to the IC's pin 9 (ANT).
Attach the power supply (9V battery) to the IC's pins 3 (VCC)
and 2 (GND).
The IC's audio output ports (pins 13 and 14) can be connected
to speakers or headphones via jumper wires.
Turn on the power source, then use a potentiometer or tuner
dial to select an FM radio station.
Use the potentiometer or volume control on your audio output
device to change the volume.
Enjoy using your handmade radio receiver to listen to FM
radio!
When dealing with electronics, keep in mind to take safety
precautions including wearing protective gear and staying away from exposed
wires. To obtain the best performance from your FM radio receiver circuit, it's
also crucial to use quality parts and carefully follow the circuit schematic.
