4. Signal conditioning element basically takes the output of the sensing element and converts it into a form more suitable for further processing, usually in the form of a DC voltage, DC current or variable frequency AC voltage. The output of the sensing element is usually too small to operate an indicator or a recorder. Therefore, it is suitably processed and modified in the signal conditioning element so as to obtain the output in the desired form that is amplify the signal and filtering the unwanted signal. i. Describe the aliasing phenomenon. ii. Suggest a solution to minimize the effect of aliasing.

One way to control power, in an electronic system is to using the PWM (pulse width modulation) method. To create an adjustable signal pulse width, one of which is used a window comparator as shown in the figure (VCC = +12 V, VEE = -12 V). If a 10 Vpp 10 kHz signal is given as an input, determine the complete output waveform by displaying the reference voltage. (compare with the input)
