Filed:

May 17, 1999

Appl. No.:

09/313435

Inventors:

Eugene Rzyski - Irvine CA 92616

International Classification:

G06F 1900

US Classification:

702111, 702 69, 330149

Abstract:

A noise measurement test system is provided for making phase noise measurements of a unit under test (UUT). The noise measurement test system comprises a variable amplifier, a variable low noise source, a variable phase shifter, a mixer, a variable low noise matching amplifier, analog-to-digital converter, a processor and a spectrum analyzer. A first low noise signal, created by the low noise source, is routed through the unit under test and variable amplifier to the mixer. A second low noise signal, also created by the low noise source, is routed through the variable phase shifter to the mixer. The mixer places the received signals in phase quadrature and outputs a measurement test signal which is routed through an analog-to-digital convertor to the processor and spectrum analyzer. The processor includes control links for adjusting the amplifier, low noise source and phase shifter to ensure that the signals received by the mixer are in phase quadrature. The processor also controls the low noise matching amplifier to ensure that there is proper impendence between the mixer and analog-to-digital convertor, and to ensure that the measurement test signal is of sufficient amplification for proper noise testing.

Appl. No.:

09/280745

Inventors:

Eugene Rzyski - Irvine CA 92616

International Classification:

G06F 1300

US Classification:

710 65, 710 68, 348574, 360 40, 360 41

Abstract:

The present invention provides for the compression of digital and analog data for storage and transmission. Analog data in the form of an analog signal is converted into a digital signal by an analog-to-digital converter. The digital signal is then converted into an analog signal having an alternating frequency by a first converter processor and an alternating frequency generator according to a predetermined conversion table. To reproduce the original analog signal, the analog signal having an alternating frequency is first converted back into a digital signal by an alternating frequency measurement means connected to a second converter processor, also in accordance with the predetermined conversion table. The digital signal is then converted to the original analog signal by a digital-to-analog converter.

Eugene Rzyski - Irvine CA 92620

International Classification:

H03F 126

US Classification:

330149, 330151

Abstract:

A cancellation circuit is provided for canceling undesirable intermodulation (IM) products in electrical circuitry. The IM cancellation circuit includes a stepping spectrum analyzer which recognizes and measures the frequencies and amplitudes of different signal components of an RF signal across a desired frequency band. This information is forwarded to a processor which contains look-up tables or the like which provides information relating to the frequencies and/or amplitudes of signal components which are intended to reside in the RF signal. By comparison of the look-up tables to the frequencies and amplitudes measured and recognized by the sweeping spectrum analyzer, the processor of the cancellation circuit is able to determine whether the signal components in the RF signal are intended âinformationâ carrying signals or unintended IM products. Where the processor has determined that a signal component is an unintended IM product, the processor controls a variable voltage controlled oscillator and variable amplifier to create a cancellation signal having an identical frequency and amplitude as the frequency and amplitude of the IM product. A phase shifter is provided to shift the phase of the cancellation signal 180 degrees with respect to the IM product and the cancellation signal is combined with the RF signal to produce an output signal having the IM product canceled.

International Classification:

H04B 126

US Classification:

455323, 455316, 455130, 455141

Abstract:

A direct downconversion receiver combines a received RF signal and a local oscillator (LO) signal to form a combined signal. The local oscillator signal is also phase-shifted by approximately 90 degrees to form a quadrature signal. A mixer forms the product of the combined signal and the quadrature signal to produce a baseband output signal.
