1. :
- A method for analog signal scrambling and unscrambling is provided for any type of phone, including cellular phones, by way of dividing the signal to disjoint frames, scrambling these frames at the analog-signal-transmission unit connected to the transmitting phone, and unscrambling and splicing the frames at the analog-signal-reception unit connected to the receiving phone, thereby recovering a continuous replica of the original analog signal.

3. :
- A method is provided for analog signal transmission for any phone, including cellular phones, by way of scrambling the signal. This is done by dividing the analog signal into disjoint frames, shaping frame boundaries to provide for frame synchronization and scrambling these frames.
-
4. :
- A method is provided for analog signal reception by any type of phone, including cellular phones, by detecting said specially designed frame boundaries in the signal to maintain frame synchronization. When frame synchronization is maintained the method provides for unscrambling the disjoint frames, splicing these frames to a continuous replica of the original analog signal and correction of previous pitch change of the signal.
