Problem (6) A discrete-time periodic signal x[n] is real valued and has a fundamental period N= 5. The nonzero Fourier series coefficients for x[n] are a, =10, a, = a, =-j6, az = a', = 5e' a, = a_s 3 %3D Express x[n] in the form x[n]= A, + A sin(@,n+4,) k=1

1. Suppose that you have a 12-bit, successive approximation register (SAR) A/D converter with a total conversion time of 100 microseconds (including sampling time). a). What is the maximum frequency of an analog signal that it can capture? b). Suppose that the converter can convert an input voltage over the range of 0 to +3.3V, what is the minimum voltage change that should be measurable by this converter? c). What is the quantization error of the ADC?

c) Sketch a basic differential amplifier circuit and discuss its mode of operation.
