Checking periodicity of signal
WebJan 9, 2024 · A periodic signal has a DC offset component if it is not centered about the x -axis. In general, the DC value is the amount that must be subtracted from the signal to center it on the x -axis. by definition: With A0 being the DC offset. If A0 = 0, the function is centered and has no offset. Half-wave Symmetry WebDetermine whether the following signals are periodic. If they are periodic, find the fundamental frequency and the period. What harmonics are present in x(t)? (a) x(t)=cos(32t+30∘)+sin(54t+45∘) (b) x(t)=2+5sin4t+4cos7t (hint, the d.c. component is not needed for checking periodicity) Question: Determine whether the following signals are ...
