Dr. Zekeriya Aliyazicioglu ECE 306 - 02 Introduction to Discrete Time Signals & Systems Quiz #1 Solution Name:__________________________January 16, 2008 1. Consider the following signal ( )2cos(100060 )π=+Daxtta. The signal ()axtis sampled with a sampling frequency 600samples/s=SF. Determine the discrete-time signal x n. b. What is the analog signal we can obtain from x nif we use 600Hz=SFfor reconstruction process? 2. The discrete-time signal 1() 4sin()10=xnn. We want to have a signal-t-noise ratio of at least 60dB. a. How many bits are needed to achieve the desired signal to noise ratio?
