Consider a signal recorded with a sampling rate of 44100Hz, where we have 300 samples of the signal. Computing the DFT magnitudes, we find the following coefficients:

X[k] = X[k+300] = \begin{cases} 1 & \text{if}~|k| = 2\\ 0 & \text{otherwise} \end{cases}

What is the frequency (in Hz) of this signal? Enter your answer below as a single number.
