There is a ON & OFF blinking of the LED light in a traffic light which is being controlled by the  switching function below: LED Switch ON time:One second at a repeated time. LED Switch off time:Three seconds between the ON times. a. Make a sketch of the signal & an expression for the blinking operation. b. Determine the Fourier coefficient i.e frequency spectra of the signal c.At time t=1,amplitude= -1,     At time t=0.5,amplitude= IV,   At t=-0.5,amplitude=IV, &    At time t=-1,amplitude=-IV.  Above is the characteristics of a voltage signal which has unity amplitude & width from a  Temperature Sensor. Make a sketch of the waveform & determine the Fourier coefficients 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.
