Abstract
An analog signal scrambler/de-scrambler includes a receiver for receiving an analog signal and converting the signal into an intermediate frequency signal. A generator generates a pseudo-random gaussian frequency distribution signal, which is multiplied with the intermediate frequency signal by a frequency converter to scramble/de-scramble the analog signal.

1-15. (canceled)
An analog signal scrambler, comprising:
- a receiver for receiving an analog signal and converting the analog signal into an intermediate frequency signal;
- a generator for generating a pseudo-random gaussian frequency distribution signal;
- and
- a frequency converter for multiplying the intermediate frequency signal and the pseudo-random gaussian frequency distribution signal, thereby scrambling the analog signal.

An analog signal de-scrambler, comprising:
- a receiver for receiving a scrambled analog signal and converting the scrambled analog signal into an intermediate frequency signal;
- a generator for generating a pseudo-random gaussian frequency distribution signal;
- and
- a frequency converter for multiplying the intermediate frequency signal and the pseudo-random gaussian frequency distribution signal, thereby de-scrambling the scrambled analog signal.

A secure analog signal transmission system, comprising:
- a transmitting unit, which comprises:
- a first receiver for receiving an analog signal and converting the analog signal into a first intermediate frequency signal;
- a first generator for generating a first pseudo-random gaussian frequency distribution signal;
- and
- a first frequency converter for multiplying the first intermediate frequency signal and the first pseudo-random gaussian frequency distribution signal, thereby scrambling the analog signal;
- and
- a receiving unit, which comprises:
- a second receiver for receiving the scrambled analog signal from said transmitting unit and converting the scrambled analog signal into a second intermediate frequency signal;
- a second generator for generating a second pseudo-random gaussian frequency distribution signal;
- and
- a second frequency converter for multiplying the second intermediate frequency signal and the second pseudo-random gaussian frequency distribution signal, thereby de-scrambling the scrambled analog signal.
