Question 33 The receiver in the block diagram is not receiving any incoming stations - the complaint is no sound. On the bench, you injected a 1 mV, 50% modulated AM signal at 455 kHz into Point D, resulting in a very loud tone in the speaker. Which of the selections below are true? A B There's probably a short in the antenna. Local Oscillator 455 KHz Intermediate Frequency (IF) Amplifier You should inject audio at Point F to test the audio amplifier. The IF amp, detector, and audio amp are working. ✔ You should inject signal at Point E to see if the trouble is in the detector stage. ✔ You should inject signal at Point B (at the carrier frequency) to test the frequency converter.
