    मैं बनाना चाहूंगा या [1 -1] की श्रेणी में सफेद शोर उत्पन्न करते हैं, लेकिन मुझे नहीं पता कि यह कैसे करना है। पसंद की मेरी प्रोग्रामिंग भाषा है matlab जहाँ तक मुझे पता है कि randn नामक एक फ़ंक्शन मौजूद है और जिसका नाम wgn (सफेद गाऊसी शोर) है उदाहरण के लिए, मैं निम्नलिखित समीकरण उत्पन्न करना चाहता हूं: 

      x (t) = 20 * sin (2 * pi * f1 * t) + 30 * कॉस (2 * pi * f2 * t) + ए 3 * सफेद शोर   
     जहां  ए 3 = आयाम  और सफेद शोर श्रेणी में है [-1 -1] कृपया मेरी मदद करें और इसे कैसे करें I मेरा भ्रम सफेद शोर से संबंधित है, दूसरों के बारे में नहीं, मान लें कि टी 1 से 100 तक बदल रहा है।   
     
     
     सफेद शोर एक  फ्लैट  (स्थिर) शक्ति वर्णक्रमीय घनत्व के साथ एक यादृच्छिक संकेत है। इसके लिए आप उपयोग कर सकते हैं अंतराल में सफेद शोर प्राप्त करने के लिए [-1] आप केवल अपनी अभिव्यक्ति में जोड़ सकते हैं  white_noise = (रैंड (1, टी) * 2-1) ।
