Assume that x[n], n = 0, 1, · · · , 11 contains all non-zero samples of a complex-valued continuous-time signal xc(t) being sampled at t = n/100, and the bandwidth of xc(t) is less than 50Hz. Also assume that the 12-point DFT of x[n] is X[k] = [0, 1, 2, 3, 2, 1, 0, 0, 0, 0, 2, 1]. A) Determine and sketch 12 uniformly spaced samples of the continuous-time Fourier transform Xc(f) of zc(t) for –50Hz B) How do you compute 64 uniformly spaced samples of Xc(f) for –50Hz 5 f < 50Hz (starting from the above 12-point DFT sequence X[k])?

How is the architecture career pathway different from the construction pathway? a. architecture involves coordinating with contractors to make sure everyone stays on schedule. b. architecture involves using tools and equipment to build something new. c. architecture involves the design process, considering the function and safety of the project. d. architecture involves evaluating the work of contractors and employees.

Price and efficiency variances, journal entries. the schuyler corporation manufactures lamps. it has set up the following standards per finished unit for direct materials and direct manufacturing labor: direct materials: 10 lb. at $4.50 per lb. $45.00 direct manufacturing labor: 0.5 hour at $30 per hour 15.00 the number of finished units budgeted for january 2017 was 10,000; 9,850 units were actually produced. actual results in january 2017 were as follows: direct materials: 98,055 lb. used direct manufacturing labor: 4,900 hours $154,350 assume that there was no beginning inventory of either direct materials or finished units. during the month, materials purchased amounted to 100,000 lb., at a total cost of $465,000. input price variances are isolated upon purchase. input-efficiency variances are isolated at the time of usage. 1. compute the january 2017 price and efficiency variances of direct materials and direct manufacturing labor. 2. prepare journal entries to record the variances in requirement 1. 3. comment on the january 2017 price and efficiency variances of schuyler corporation. 4. why might schuyler calculate direct materials price variances and direct materials efficiency variances with reference to different points in time
