<s>[INST] Given a signal as a two dimensional array in Ruby, find the median of this signal, by treating each row of the signal independently.

## Step 1: Define the problem
The problem is to find the median of each row in a given 2D signal array.

## Step 2: Understand the input and output
The input is a 2D array representing the signal, where each row is treated independently. The output should be an array of median values, one for each row.

## Step 3: Plan the approach
To find the median of each row, we will first sort the rows, and then calculate the median based on the number of elements in the row (whether it's odd or even).

## Step 4: Write the Ruby code to solve the problem
We will use the built-in methods for sorting arrays in Ruby and write a method to calculate the median.

```ruby
def find_median_of_signal(signal)
  signal.map do |row|
    sorted_row = row.sort
    size = sorted_row.size
    if size.odd?[/INST]
