In 32-bit DDFS system, quarter wave symmetry technique is used to store only one  quarter of the sine wave, whereas the ROM look-up table is partitioned into three 4-bit sub-ROMs based on angular decomposition technique and trigonometric identity. Exploiting the advantages of sine-cosine symmetrical attributes together with XOR logic gates, one sub-ROM block can be removed from the design. These techniques, compressed the ROM into 368 bits with 534.2:1 compressed ratio.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659566394\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659566394","offer_id":39448709431389,"sku":"9783659566394","price":32.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f9421f72-eaf9-4024-93c5-f23838337534.jpg?v=1770099724","url":"https:\/\/shop.autorenwelt.de\/products\/a-novel-rom-design-for-high-speed-direct-digital-frequency-synthesizer-von-salah-hassan-alkurwy-sawal-hamid-md-ali-md-shabiul-islam","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
