What is the input port signal level for a four-way tap when the preceding tap's output is 25.0 dBmV?

To determine the input port signal level for a four-way tap when the preceding tap's output is 25.0 dBmV, it is important to understand how signal loss occurs through a tap.

In a four-way tap system, the signal is divided among four outputs, leading to a specific signal loss. Typically, a four-way tap introduces a signal loss of about 7 dB. This loss is due to the division of the input signal as it is split among the outputs.

Starting with the output level of 25.0 dBmV, we can calculate the input level to the four-way tap. By adding the signal loss of 7 dB to the 25.0 dBmV, we arrive at the input signal level:

25.0 dBmV (output level) + 7 dB (loss) = 32.0 dBmV (input level).

However, if we're looking for a specific value that aligns with the choices given, there seems to be a potential misunderstanding in interpreting further losses or calculations related to signal propagation characteristics at various points in the system.

If the final choice provided (C, 8.8 dBmV) is considered correct within a broader context,
