Quiz in Analog Transmission
Question 1. ________ uses two carriers, one in-phase and the other quadrature.
Question 2. In _______, the peak amplitude of one signal level is 0; the other is the same as the amplitude of the carrier frequency.
Question 3. If the bit rate for an ASK signal is 1200 bps, the baud rate is ________.
Question 4. If the baud rate is 400 for a QPSK signal, the bit rate is ________ bps.
Question 5. The constellation diagram of BASK has ______ dots.
Question 6. AM and FM are examples of ________ conversion.
Question 7. The Federal Communications Commission (FCC) allows ______kHz for each AM station.
Question 8. In _____ transmission, the carrier signal is modulated so that its amplitude varies with the changing amplitudes of the modulating signal.
Question 9. Given an AM radio signal with a bandwidth of 10 KHz and the highest-frequency component at 705 KHz, what is the frequency of the carrier signal?
Question 10. In _____ transmission, the frequency of the carrier signal is modulated to follow the changing voltage level (amplitude) of the modulating signal. The peak amplitude and phase of the carrier signal remain constant, but as the amplitude of the information signal changes, the frequency of the carrier changes correspondingly. |
