Product Overview
The FM Receiver Demonstrator is a precision-engineered educational kit designed to illustrate fundamental principles of frequency modulation radio technology. Built on a durable PCB platform with high-grade metal components, this demonstrator provides clear signal reception across standard FM bands (88-108 MHz). The kit features adjustable tuning capabilities that allow users to manually select stations while observing signal strength variations. Its open-circuit design enables visual tracing of signal paths from antenna input through the demodulation stages, making it ideal for hands-on learning. The receiver incorporates a sensitive detector circuit that converts radio frequency signals into audible audio output through a built-in speaker or headphone jack. With its robust construction and precise calibration, this demonstrator maintains consistent performance across repeated experiments. The educational-grade components ensure reliable operation while withstanding frequent handling in laboratory environments. The kit’s compact form factor makes it suitable for benchtop use while providing all necessary connection points for external measurements and analysis.
FAQs
1. What frequency range does this FM receiver demonstrator cover?
This kit is designed to receive standard FM broadcast signals in the 88-108 MHz range, covering all commercial FM radio stations.
2. Can this demonstrator be connected to external measurement equipment?
Yes, the kit provides test points at various stages of the receiver circuit for connecting oscilloscopes or multimeters to analyze signal characteristics.
3. What power source is required for operation?
The demonstrator typically operates on standard 5V DC power, which can be provided through a USB connection or external power adapter.
4. Is any assembly required before first use?
Minimal assembly is needed – primarily connecting the antenna and power source. All critical components come pre-soldered and tested.
5. How does this differ from commercial FM receivers?
Unlike sealed commercial units, this demonstrator features an open design that exposes all circuit stages for educational observation and measurement purposes.
