रेडियो सेट प्रयोग
Gelsonlab HSTM-052 शिक्षा विज्ञान खिलौने रेडियो सेट प्रयोग
रेडियो सेट प्रयोग is composed of antenna receiving radio wave signal, tuning variable capacitance of frequency modulation, internal high-frequency amplification of IC, oscillation, mixing, power amplifier module and loudspeaker. Through experiments, we can understand the structure and principle of radio.
