Maxfiner has worked in the wireless communication department of Huawei Communication Technology Co., Ltd., and has many years of experience in engineering project development. It also has algorithm theory research, simulation verification, and corresponding hardware design implementation capabilities. It has practical experience in all aspects of communication physical layer development and design. .
Convolution is a basic concept of signal processing. One of the most important aspects of its implementation is perhaps the following sentence: The convolution of the time domain corresponds to the multiplication of the frequency domain. In this sentence, or in other words, this concept will be fully reflected in many applications, such as frequency domain equalization, such as channel estimation, such as filtering analysis. The convolution formula, at first glance, seems a bit awkward. Why is it such a form, why is one of the signals to be flipped?
Through the above derivation, and then experience and observe the convolution formula, perhaps there is no such unintuitive feeling.

Deluxe Rice Cooker was one of electric type rice cooker , but it`s the most popular type of electric rice cooker . especially famous in Southeast Asia area with its good appearances with various functions. Not only its outer shell could be customized with different demands, but also it speeding cooking , saving times and electricity, enhancing our lifestyle
The inner pot is made of solid and durable aluminum alloy of high intensity , such as non-stick inner pot , stainless steel inner pot and honeycomb patterned inner pot with non-stick coating.
There are some models that use stainless steel instead of aluminium .Various other materials, such as copper, pure carbon, ceramic, and diamond powder coating, may be used for higher heat conductivity or better taste.
Multifunction , can cooking rice, soup and much more. added cooking versatility with supplied steam tray.
Some rice cookers have settings for congee, a type of rice porridge called okayu in Japanese, Juk in Korea, and zhou in Chinese.
More elaborate recipes are possible using a rice cooker, and there are cookbooks devoted entirely to dishes prepared using a rice cooker. It is possible to cook soups, stews or sponge cakes in electric rice cookers. By simply adding ingredients and setting it to "warm", a rice cooker cooks the contents at about 65 Â°C (150 Â°F). In a few hours, the stew is fully cooked and ready to eat.
