Explanation

According to the textbook, bandwidth is the difference of maximum and minimum frequency contained in the composite signals. The signal has frequencies between 500 MHz and 1 GHz, so the calculation is straightforward: Bandwidth = Maximum frequency - Minimum frequency = 1 GHz - 500 MHz = 500 MHz.

Solution Steps

  1. Step 1: Identify the given values — Minimum frequency = 500 MHz, Maximum frequency = 1 GHz = 1000 MHz

  2. Step 2: Apply the bandwidth formula — Bandwidth = Maximum frequency - Minimum frequency

  3. Step 3: Calculate — Bandwidth = 1000 MHz - 500 MHz = 500 MHz
