Consider the binary PAM system using a triangular pulse shape of width 2/r_b, as shown below. A pulse with a positive amplitude (+1 volt) will be transmitted for a "1" and a pulse with a negative amplitude (-1 volt) will be transmitted for a "0". Draw the transmitted waveform for a system sending the data pattern "10110" at a transmission speed of 100,000 bits per second. Label the time and amplitudes for your sketch Assuming that the energy spectral density for a single triangular pulse is the same as the power spectral density for a typical series of triangular pulses, what is the BW? (assume that is 93% of power must be in band). Suppose the channel attenuates the waveform amplitude by 80%. What is the noise margin for the second bit (assuming perfect synchronization) Suppose the receiver is out of synchronization and that it samples the received w 2 sec after the optimum time. Using 80% attenuation, what is the noise margin of the second bit
