Explain why the signal in SWV is peak-shaped while in NPV it is sigmoidal.
In the case of SWV, a stepwise varying potential is applied. In each potential step, ES, a symmetrical double pulse will get superimposed. Thus the shape of the signal is peak shaped.
In the case of NPV, it involves the application of pulses of increasing amplitude that are superimposed in a constant potential, so the shape of signal is sigmoidal.
Explain why the signal in SWV is peak-shaped while in NPV it is sigmoidal.
Explain why the Fe 2p spectrum shows two peaks, while the P 2p show one peak. (XPS)
Explain the significance of the peak to peak voltage in terms of Vac production and why you divide by two to obtain voltage amplitude.
A sine wave signal is displayed on the screen of an oscilloscope. 6 peak-to-peak divisions are measured vertically and 8 peak-to-peak divisions horizontally. The voltage control is on the 2 volts / div scale and the sweep control is on the 5ms scale. The signal period is: a. 0.03 seconds b. 0.04 seconds c. 4 seconds d. 0.005 seconds

Problem 1: The peak to peak amplitude of a sinusoidal signal sin(t) is quantized into four levels of [-0.75,-0.25, 0.25,0.75]. If the actual signal values are [0.36, 0.24, 0.08,-0.74,-0.96,-0.10], what will be their quantized values?
