The terms RMS, MSE, and SNR were used in Section 3.6.2 in connection with quan- tization. These terms are important in many aspects of signal processing besides quantization. (a) Explain in words the meaning of RMS, MSE, and SNR. What physical charac- teristic do they represent? (b) MSE is defined as MSE = (() – x(1)*". N- Explain each term of the equation. (c) RMS is defined as RMS =E**) Explain each term of the equation. (d) SNR in decibels is de fined as x*(n) SNR = 10 logio

What is coupled magnitudes? What is the significance of this difference in the coupled magnitudes to the lay-out of circuit fast signals?

7-22 Abasehand signal with frequency components from near de to 15 kHz frequency modulates a 200-kHz carrier, and the frequency deviation is +3 kHz. The signal is applied as the input to a cascade of two frequency triplers and one frequency doubler. Determine the output (a) center fre- quency, (b) frequency deviation, and (c) deviation ratio.
