Signal original form to a waveform expressed as a current ("I") or a voltage ("V"), or an electromagnetic waveform, for example, an optical signal or radio transmission. Once expressed as an electronic signal, the signal is available for further processing by electrical devices such as electronic amplifiers and electronic filters, and can be transmitted to a remote location by electronic transmitters and received using electronic receivers. In Electrical engineering programs, a class and field of study known as "signals and systems" (S and S) is often seen as the "cut class" for EE careers, and is dreaded by some students as
Electronic fluency device i.e. a reduction in stuttering after the stutterer removes an electronic fluency device, while others have not. The effective of electronic fluency devices as measured by qualitative measures and ratings by stutterers have also been made. Studies show that some stutterers report improved fluency and confidence about speaking, and less severe stuttering and some carryover effects; the device is perceived as being particularly useful on the telephone. They reported that the device was difficult to use in noisy situations as the device amplifies all voices and sounds, and some acclimatization to the use of the device over time. Qualitative reports
