The document provides guidance for writing a lab report on building an AM radio receiver and audio amplifier. It outlines the key sections and content required in the report, including:
1) Explaining how the AM radio receiver works through descriptions of its tuning, demodulation, and amplification circuits.
2) Recording the results of testing the radio reception and explaining the factors that affect reception quality.
3) Explaining how the audio amplifier works with the speaker to amplify the radio signal.
4) Demonstrating AM transmission by receiving a lab-generated AM signal and explaining how AM transmission modulates an audio signal onto a carrier wave.
17. AM reception in the Leicester area – one of the many supporting links that can be found online. http://mysite.wanadoo-members.co.uk/freq_find/tc/leicester.html
18. AM Transmission Demonstration The main section of the report should end with the recording of the AM transmission demonstration that will take place in week 11. We will generate an AM transmission signal in the lab and test to see if your radios can receive the signal and play it through the amplifier.
19. The section of the report on the AM transmission demonstration should be used to explain to the reader how AM transmission works – how a higher frequency carrier wave is modulated by a low frequency audio information signal.
