Extracted text: A base band signal used in European standard voice grade communication is represented by a band limited CT signal of triangular shape spectrum is sampled at fs=10 kHz. The spectrum of the sampled signal shows 2 kHz separation between the original signal spectrum and the next сору. (a) Find the maximum frequency in a CT signal. (b) Draw the spectrum of the sampled signal.
