! Required information x(t) A1 Az- The given figure is a graph of one fundamental period of a periodic function x(1). A CTFS harmonic function cxk] is found based on the representation time being the same as the fundamental period To, where A1 = 5, A2 = -3, and To = 5. If the representation period is changed to 3T0, determine the new numerical value of cx(0]. The new numerical value of c0] is 0.33 *

If we have a discrete time sinusoid as shown in the figure:Can you determine another sinusoidal signal with a digital frequency of 0 < omega < 2phi with the same sample size?.
Example: If the analog signal to be quantized is a sinusoidal waveform, that is x(t) = Asin(2 x 103nt) and if the bipolar quantizer uses m bits, determine the SNR in term of m bits
thanks again in advance
