$$\frac{d^2y}{dx^2} + 5 \frac{dy}{dx} - 6y = 0$$

$$\frac{d^2y}{dx^2} - 5 \frac{dy}{dx} + 6y = 0$$

$$\frac{d^2y}{dx^2} + 5 \frac{dy}{dx} + 6y = 0$$

$$\frac{d^2y}{dx^2} - 5 \frac{dy}{dx} - 6y = 0$$

amplitude spectra are identical and their phase spectra are also identical

amplitude spectra are identical but their phase spectra are different

amplitude spectra are different but their phase spectra are identical

Decrease continuously

Increase continuously

First increase, becomes zero and then decrease

First decrease, become zero and then increase

May be $$\leq 1$$ depending on the distance between the two stations

is always greater than 1

Does not depend on the distance between the two stations
