What is the total bandwidth of a transmitter using A-2 emission with a modulating frequency of 800 Hz and a carrier frequency of 500 kHz?

• A. 1600 Hz
• B. 1.6 kHz
• C. 800 kHz
• D. 1000 kHz

Answer: (A)

In evaluating the total bandwidth of a transmitter utilizing A2 emission, which represents amplitude modulation of a carrier frequency, it is critical to recognize how the modulation type impacts the required bandwidth. For amplitude modulation (A2), the total bandwidth is essentially twice the highest modulating frequency. In this case, the modulating frequency is given as 800 Hz. Therefore, to determine the total bandwidth, you simply multiply the modulating frequency by two, which results in: Total Bandwidth = 2 × Modulating Frequency = 2 × 800 Hz = 1600 Hz. This calculation aligns with the characteristics of amplitude modulation, where the sidebands created account for twice the modulation frequency above and below the carrier frequency, hence leading to the total bandwidth of 1600 Hz. Thus, the correct choice accurately reflects the computed bandwidth for this scenario.
