摘要： An apparatus and method of improving the quality of a speech codec are provided. In the method, a first energy of a signal decoded by a low-band codec is calculated, and a second energy of a signal decoded by a low-band enhancement mode is calculated. Then, when the first energy is less than a first threshold value or less than a product of the second energy and a second threshold value, a size of the decoded signal is scaled. Accordingly, generation of a quantization error with respect to a silence segment is reduced.

摘要： Provided is a fuel cell including an anode electrode, a cathode electrode, and an electrolyte/ion exchange membrane between the anode electrode and the cathode electrode. The cathode electrode uses an iron redox couple as an oxidizer. The iron redox couple is regenerated by an oxidizing substance. The fuel cell does not need a noble metal catalyst, is thus economical in manufacturing costs, and has high power density, thereby improving energy conversion efficiency. Furthermore, the fuel cell is capable of decomposing an oxidizing substance, such as NOx, Cl2, Br2, or O3.
