The bandwidth of a composite signal is the difference between the highest a the lowest frequencies contained in that signal. If a periodic signal is decomposed into five sine waves with frequenci of 100, 300, 500, 700, and 900 Hz, what is its bandwidth? Draw the spectru assuming all components have a maximum amplitude of 10 V. (a) A periodic signal has a bandwidth of 20 Hz. The highest frequency (b) 60 Hz. What is the lowest frequency? Draw the spectrum if the signal contai all frequencies of the same amplitude. A non-periodic composite signal has a bandwidth of 200 kHz, with (c) middle frequency of 140 kHz and 20 V as peak amplitude. The two extrer frequencies have amplitude of 0. Draw the frequency domain of the signal.

Fourier Transform

In mathematics, the Fourier transformation is a mathematical transformation that rotates responsibilities by using region or time into tasks depending on the local or temporal frequency, such as the rendering of a musical track in step with existing volumes and frequencies. The term Fourier amendment refers to each illustration of the frequency range and the mathematical functionality related to the representation of the frequency domain and the function of space or time.
