In this invention, a new method for audio compression has been developed. This results in high speed and high accuracy compression of audio signals. This method is based on adapting the single-bit delta modulator with a high performance step-size adapter. The adapter enables high speed tracking of the audio signal and high accuracy compression. This results in improving the compression rate and speed of the conventional compression devices. The adapter is also used in analog-to digital conversion. Again, the adapter results in high speed tracking and high accuracy conversion of analog signals. The invention can be used in all digital devices such as mobile phones, digital TV, Voice over Internet Protocol (VoIP), Personal Digital Assistant (PDA), PC Sound Cards, digital recorders, etc. The invention can increase the quality of audio signals and reduce the cost of such devices.

This invention introduces new methods for regulating the power of transmission power of wireless devices and base-stations. Wireless devices tend to use the same transmission power when they talk to each other. As a consequence, one device can cause interference to other in the same cell. Also, they consume more energy than necessary. This invention enables these devices to use the right power when talking to the base-stations. This results in less interference with other devices and less power consumption. As a consequence, the invention can improve the quality of the communication system and increase the battery life of the wireless devices. The invention can be used in all new wireless systems such as mobile networks, personal wireless networks, and local area networks, and cordless phones.
