Introduction The frequency response is a representation of the system's response to sinusoidal inputs at varying frequencies. The output of a linear system to a sinusoidal input is a sinusoid of the same frequency but with a different magnitude and phase. The frequency response is defined as the magnitude and phase differences between the input and output sinusoids.
The frequency response comprises of two parts: 1. Gain Response 2.Phase Response The frequency response of a system …

…resistance of the parallel components R2 and C is 100KW || 159KW = 61.3KW Therefore the voltage can be calculated across the capacitor.
The voltage drop across R1 = 3.1V The voltage drop across R2|| C = 1.9V As the frequency increases the reactance of the capacitor decreases, this means that the voltage drop across R2 || C will decrease as the frequency of the input increases. This can be seen from the Table 1 of Results in the experimental procedure.
