The option 1,2,3 and 4 are matches with the option B,A,D,and C respectively. Oscillator, transmitting antenna, microphone, or modulator are the type of the radio transmission devices.
What is microphone?
Microphone is a radio transmission devices picks up sound waves and converts them into suitable electric current with the same pattern as the sound waves.
The functions of the following radio transmission devices are as follows;
1. Oscillator- (B) Enables the waves produced by the antenna to “carry” the pattern of the sound waves picked up by the microphone.
2. Transmitting antenna-(A) Sends out radio waves having the same frequency as the current supplied by the oscillator.
3. Microphone-(D) Picks up sound waves and converts them into suitable electric current with the same pattern as the sound waves.
4. Modulator-(C) Converts a direct current into a high-frequency alternating current.
Hence, the option 1,2,3 and 4 are matches with the option B,A,D,and C respectively.
