WebJun 26, 2024 · 1 Answer. Yes, because if the determinant is zero, then the system is either inconsistent (no solutions), or it has infinitely many solutions. Assuming the determinant is defined (which means that you must have a square matrix), you can just take the inverse of the matrix. If the inverse exists, this will give you exactly one, unique solution. WebNov 4, 2024 · Return loss vs. reflection coefficient definition. Because the reflection coefficient Γ < 1, then the return loss will have a positive dB value.
