In Figure P10.28-1, we show a system for spectral analysis of a signal x_c(t), where

For the most general choice of the multiplier coefficient a_l , determine the choice for L and R which will result in the smallest number of multiplies per second.

(b) In Figure P10.28-2, we show another system for spectral analysis of a signal x_c(t), where

Listed below are two possible choices for M, four possible choices for ω_k, and six possible choices for the coefficients a_l. From this set identify all combinations for which Y_k[n] = X_k[n], i.e., for which both systems will provide the same spectral

analysis. There may be more than one.
