Abstract: A direct power output digital to analog conversion of digital audio signals operates to directly convert digital audio signals into an analog power audio output signal capable of driving a speaker, such that there is no need for further amplification or modification of the audio output signal after the direct power output digital to analog conversion of the digital audio signals. The direct power output digital to analog conversion incorporates a digital-to-analog converter within the same feedback circuit as a current-to-voltage power amplifier by using a single resistive feedback network to supply the feedback signal from the output terminal of the current-to-voltage power amplifier to the summing junction of the same current-to-voltage power amplifier.

Abstract: A method and system is provided for a digital audio system to reconstruct a digital audio signal using time domain interpolation and direct power digital-to-analog conversion. A signal processor performs the time domain interpolation on an original digital audio signal to allow for the proper recreation of the original audio signal and a direct power output digital-to-analog converter generates an analog power audio output signal from the interpolated digital audio signal that can directly drive a speaker to produce the sound waves represented by the audio output signal. The signal processor and direct power output digital-to-analog converter allow a digital audio system to more precisely reconstruct an analog power output audio signal from a digital audio signal such that there is no need for further amplification of the audio output signal and such that there will be no perceptible difference between the reconstructed digital signal and the original analog signal.

Abstract: An apparatus for the domain interpolation of digital audio signals includes a signal processor apparatus to reconstruct the digital audio signal. The signal processor apparatus includes a receiver for receiving a digital audio signal, a decoder for demodulating the signal, a central processing unit for performing a time domain interpolation on the decoded signal to produce an interpolated data signal having an increased sampling rate over the digital audio signal, and a digital-to-analog converter for converting the interpolated data signal into an analog output signal that may be transmitted to an amplifier for output through a speaker. The signal processor apparatus achieves an oversampling rate and digital to analog conversion that will allow a digital audio system to more precisely reconstruct an analog audio signal from a digital audio signal such that there will be no perceptible difference between the reconstructed digital signal and the original analog signal.

Abstract: A telecommunication system and method for communicating communication signals between various stations over a selected carrier medium. An improved encoder and method is provided for compressing a communication signal into a selectively formatted encoded signal to facilitate its transmission over the selected carrier medium. The method is particularly useful for encoding fax and modem data signals which do not exhibit the harmonics of a voice signal. A decoder and method for reconstruction of the encoded signal are also provided.

Abstract: A private telephone line expander is disclosed which receives two analog voice inputs. Both input signals are digitized, compressed using full period splicing, and converted back to analog for transmission. One is shifted to the upper half of the telephone line bandwidth. The other remains in the lower half. Both are transmitted on the same telephone line. When received both signals are expanded to normal telephone bandwidth and can be connected to two different telephones. DTMF signals are transmitted with each voice transmission.
