Zusammenfassung:PCT No. PCT/DE94/01479 Sec. 371 Date Jun. 12, 1996 Sec. 102(e) Date Jun. 12, 1996 PCT Filed Dec. 13, 1994 PCT Pub. No. WO95/17039 PCT Pub. Date Jun. 22, 1995A high frequency arbitrarily modulated signal and noise generator utilizes digital numerically controlled oscillators providing interbusiness directly to an adder and which are phase modulated. The digital adder feeds a digital analog converter, eliminating the need for a digital multiplier while providing amplitude or phase modulation with high resolution and at high processing speeds.
