The AM And FM Signal Generator from AGN Enterprises is an educational electronic test instrument designed for generating suitable amplitude-modulated (AM), frequency-modulated (FM), and RF signals for communication engineering experiments, receiver testing, demonstrations, and laboratory applications. It provides students with a practical signal source for understanding modulation techniques and testing compatible communication circuits.
Amplitude modulation and frequency modulation are fundamental techniques used in analog communication systems. In AM, the amplitude of a carrier signal varies according to the modulating information signal. In FM, however, the instantaneous frequency of the carrier varies according to the modulating signal. Therefore, students can use the generator to study and compare the behavior of these two important modulation methods.
Moreover, the instrument provides a convenient signal source for suitable experiments involving radio receivers, modulation and demodulation circuits, tuned amplifiers, communication trainers, and RF circuits. Depending on the supplied model, users can select appropriate frequency ranges, modulation modes, and output levels required for compatible laboratory experiments. Consequently, learners can observe how communication circuits respond under different signal conditions.
The generator is particularly useful for practical studies involving carrier signals, modulating signals, modulation depth, frequency deviation, receiver alignment, signal tracing, and communication circuit testing. Furthermore, students develop practical skills in frequency adjustment, signal connection, waveform observation, circuit testing, and measurement.
For additional educational resources covering communication and radio technology, students can refer to the IEEE Communications Society.
The laboratory signal generator provides a structured signal source for communication and electronics experiments. In addition, instructors can use it to demonstrate the differences between amplitude and frequency modulation while testing suitable receiver and modulation circuits.
