interpolator with an upsampling factor L=3. Determine the output sequence.
ii.) Draw the block diagram of the interpolator (with an upsampling factor L=3)
by correctly mentioning the cut-off frequency of the interpolation filter to be

used, if the input signal is bandlimited to a frequency of |w| < 7 Substantiate the

need for the interpolation filter with necessary diagrams and explanations.
Differentiate between truncation and rounding with an example.
Explain the limit cycle oscillation in recursive filters with an example.
