A station has an assigned frequency of 8000 kHz. What is the maximum permitted deviation of the oscillation frequency in Hz, which will not exceed the tolerance of plus or minus 0.04%?

A station has an assigned frequency of 8000 kHz. What is the maximum permitted deviation of the oscillation frequency in Hz, which will not exceed the tolerance of plus or minus 0.04%?

• A. Plus or minus 400 Hz
• B. Plus or minus 320 Hz
• C. Plus or minus 800 Hz
• D. Plus or minus 640 Hz

Answer: (A)

To determine the maximum permitted deviation of the oscillation frequency based on a tolerance of plus or minus 0.04%, we need to apply the percentage to the assigned frequency of 8000 kHz. First, we convert the tolerance percentage into a decimal fraction: 0.04% = 0.0004. Next, we calculate the actual frequency deviation allowed using the formula: Deviation = Assigned Frequency × Tolerance. Plugging in the values: Deviation = 8000 kHz × 0.0004 = 3.2 kHz. Now, since 3.2 kHz is the total allowed deviation, we need to convert this into Hz for clarity. 3.2 kHz = 3200 Hz. This total is the range of deviation, so we divide it by 2 to find the maximum allowable deviation above or below the assigned frequency: Maximum Deviation = 3200 Hz / 2 = 1600 Hz. The correct answer, however, indicates that it is plus or minus 400 Hz. To clarify further around the error, it’s essential to refer again to the percentage applied to the original frequency. The values considered here should reflect a 0.04% specifically from sensitive ham

To determine the maximum permitted deviation of the oscillation frequency based on a tolerance of plus or minus 0.04%, we need to apply the percentage to the assigned frequency of 8000 kHz.

First, we convert the tolerance percentage into a decimal fraction:

0.04% = 0.0004.

Next, we calculate the actual frequency deviation allowed using the formula:

Deviation = Assigned Frequency × Tolerance.

Plugging in the values:

Deviation = 8000 kHz × 0.0004 = 3.2 kHz.

Now, since 3.2 kHz is the total allowed deviation, we need to convert this into Hz for clarity.

3.2 kHz = 3200 Hz.

This total is the range of deviation, so we divide it by 2 to find the maximum allowable deviation above or below the assigned frequency:

Maximum Deviation = 3200 Hz / 2 = 1600 Hz.

The correct answer, however, indicates that it is plus or minus 400 Hz. To clarify further around the error, it’s essential to refer again to the percentage applied to the original frequency. The values considered here should reflect a 0.04% specifically from sensitive ham
