Assume a signal is band limited to 1KHz but there is an unwanted component present at 3.2KHz. If the desired signal is a 100Hz sinusoid of amplitude 3V p-p centered around 2.5V and VREF=5V, determine the magnitude of the aliased signal and the frequency of the aliased signal if the input is sampled at 2KHz and the amplitude of the undesired 3.2KHz signal is 0.5V p-p (and also centered around 2.5V). So, I am using this equation: and I have fsamp set as 2KHz. What would f be in this equation? and what is k? and how am I determine the magnitude of the aliased signal? Any help is appreciated. Thanks!
