Two-channel multi-tone audio frequency sinusoidal & noise signal generator is intended for adjusting and measuring parameters of audio equipment. Independent channels frequency and amplitude controls. A step of frequency setting is 0.00001 %; level - 0.001 dB; phase - 0.001 degree. The minimum coefficient of nonlinear and intermodulation distortion, precision, stability and range of frequency are limited only to quality of the used sound card.

Allows easy performance of date calculations. Adds a number of days to a date, calculates the number of days between two dates and converts among Gregorian dates, Julian dates, ISO Week dates, Hermetic Leap Week dates, Julian day numbers and ordinal dates. Weekends may be included or excluded. It has a built-in programming language, with control structures, variables and functions, which allows users to run their own date-processing programs.

Weekend days may be included or excluded. Program is bilingual: English and German.

The Sun is the most prominent feature in our Solar System. It is the largest object and contains approximately 98% of the total solar system mass. One hundred and nine Earths would be required to fit across the Sun's disk. Its outer visible layer has a temperature of 11000’F. This layer has a mottled appearance due to the turbulent eruptions of energy at the surface. Want to have a look now? Download this outstanding 3D screensaver.
