Consider a D/A converter for audio signals consisiting of a zero-order-hold interpolator followed by a continuous- time lowpass filter with positive passband between 0 and 20KHz and stopband starting at fa = 40KHz. = Assume we want to convert a digital signal originally sampled at 16KHz. What is the minimum oversampling factor that we need to use?
