Please explain part 2 thoroughly. Thanks! Consider a message signal m(t) with power of 20 mW that is applied to an analog-to-digital converter, with dynamic range of -1 to 1 volt. a) If uniform quantization is utilized, and the minimum signal-to-quantization-noise (SQNR) is 43 dB, determine the minimum number of bits required, and the corresponding SQNR obtained with this quantizer. b) Repeat Part (a) if a u-law compander is used with u-100. c) If the power of the signal m(t)...
The signal yb(t) = (V + v(t))w(t), where v(t) = V cos (2πt/T) and w(t) = u(t + T/2 ) − u(t − T/2), is called a Hanning window function. Using a computer, calculate the percent of the signal’s total energy that is located in its side lobes. A side lobe is any part of a function that is not a central lobe, and a central lobe is the nonzero portion of a function between its first negative and positive...
