Експеримент са радио пријемником
Гелсонлаб ХСТМ-052 Експеримент са научним играчкама за образовање
Експеримент са радио пријемником 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.
