Final answer:
The nonzero Fourier series coefficients of a continuous-time periodic signal depend on the specific waveform and cannot be determined without more information.
Step-by-step explanation:
The nonzero Fourier series coefficients for a continuous-time periodic signal can be determined by analyzing the waveform and finding the amplitudes of its harmonics. In this case, the fundamental period of the signal is 8. This means that the signal repeats itself every 8 units of time. The Fourier series representation of a periodic signal can be calculated using the formula:
x(t) = a0 + sum(a_n * cos((2*pi*n*t)/T) + b_n * sin((2*pi*n*t)/T))
Since the signal is real-valued, the coefficients b_n will be zero, and we only need to find the coefficients a_n. The nonzero Fourier series coefficients for x(t) will depend on the specific shape and properties of the signal. Without further information about the waveform, it is not possible to determine the values of the nonzero coefficients.
