the highest frequency for a message signal is 15 Hz. it AMmodulates a carrier of 500 kHz. Plot the frequency spectrum of the modulated signal.is the highest frequency component of the modulated signaljust 15+500000 Hz? Can frequency add that way?
Draw the logic diagram of a four-bit register with four D flip-flops and four 4 X 1 multiplexers with mode selection inputs s1 and s0. The register operates according to he following function table
A family selects two phones from a box containing cellphones: four are Nokia, marked N1, N2, N3, and N4. The other three are Samsung, marked S1, S2, and S3. Two phones are picked randomly in succession without replacement.
