Essays on Signal Processing

The main goal of speech modification is the control of non-linguistic information of various speech signals, as, for instance, voice quality and/or voice individuality. The term speech modification is usually used to refer to the different modifications, which may be applied to the sound produced by people. (McAulay and Quatieri, 1986) Speech modification is used in a big range of areas, such as speech synthesis, film and music industry, voice editing, dubbing, toys, chat rooms, games, communications (interpreting telephony, helium speech), voice pathology (voice restoration), high-end hearing aids, other applications (for example, confuse speaker identification systems). The process of ...

Signal filtering is one of the most fundamental practices in signal processing. The filters are widely incorporated in the signal processing circuits due to their indomitable role in data acquisition and also to get rid of all the unnecessary signals and frequencies which interfere with the quality of the main signal. These unwanted signals are commonly referred to as noises. Once the signal has been filtered, they are then processed as either analog or digital depending on the signals application. Some signals are however weak and thus require an amplification circuit so that the filtering circuits can be consistent. ...

Electrical engineering is the largest technological filed in the world. The field offers educational and research opportunities in electronics, photonics, and nanotechnology; sensors, computers, and networking; and communication and control, signal and image processing. Competent electrical engineers have vast expertise in design and development of one or more careers of the discipline: telephone networks and switching systems, receivers and transmitters of radio, television and communication systems, generation and distribution of power, computer systems among others (Chen, 123). Electrical engineers implement, test, install and maintain large-scale electronic devices and machinery used in manufacturing, generation of electric power and transmission. An ...
