The state equation and the output equation of a control system are given below; \[\begin{array}{l} \mathop x\limits^ \cdot = \left[ {\begin{array}{*{20}{c}} { - 4}&{ - 1.5}\\ 4&0 \end{array}} \right]x + \left[ \begin{array}{l} 2\\ 0 \end{array} \right]u\\ y = \left[ {1.5\,\,\,0.625} \right]x \end{array}\] The transfer function representation of the system is
In a baseband communications link, frequencies upto 3500 Hz are used for signaling. Using a raised cosine pulse with 75% excess bandwidth and for no inter-symbol interference, the maximum possible signaling rate in symbols per second is
