Practical AM diode detector

1. Skip distance:-Skip distance is defined as the shortest distance from a transmitter, measured along the surface of earth at which a sky wave of fixed frequency returns back to the earth.

2. Maximum usable frequency: The limiting frequency when the angle of incidence is other than the normal is known as maximum unstable frequency. MUF= fc secθ.

3.Virtual height:-The incident and refracted rays follow paths that are exactly the same as they have been if reflection had taken place from a surface located at a greater height, called Virtual height of this layer.
