13. We want to implement a 6-point decimation-in-time FFT using a mixed radix approach. One option is to first take three 2-point DFTs, and then use the results to compute the 6-point DFT. For this option: (a) Draw a flowgraph to show what a 2-point DFT calculates. (b) Also, fill in the parts of the flowgraph in the figure below involved in calculating the DFT values $X_0$, $X_1$, and $X_4$. (c) How many complex multiplications does this option require? (Multiplying a number by $-1$ does not count as a complex multiplication.) A second option is to start with two 3-point DFTs, and then use the results to compute the 6-point DFT.

You believe that IRP presently exists. The nominal annual interest rate in Mexico is 11 percent. The nominal annual interest rate in the United States is 2 percent. You expect that annual inflation will be about 3 percent in Mexico and 5 percent in the United States. The spot rate of the Mexican peso is $0.11. Put options on pesos are available with a one-year expiration date, an exercise price of $0.1108, and a premium of $0.011 per unit. You will receive 1 million pesos in one year. Do not round intermediate calculations. Round your answers to the nearest dollar. a. Determine the expected amount of dollars that you will receive if you use a forward hedge. $ _____ b. Determine the expected amount of dollars that you will receive if you do not hedge and believe in purchasing power parity (PPP). $ _____ c. Determine the amount of dollars that you will expect to receive if you believe in PPP and use a currency put option hedge. Account for the premium you would pay on the put option. $ _____
