Find the Inverse Laplace Transform of F(s) = s²/(s-2)³

For the signal, x(t) = log(cos(a*pi*t+d)) for a = 50 Hz, what is the time period of the signal, if periodic?

What process is used to derive a discrete time signal from a continuous time signal?

A CDMA system consists of 15 equal power users that transmit information at a rate of 10 kbps, each using a DS spread spectrum signal operating at a chip rate of 1 MHz. The modulation scheme is BPSK. The Processing gain is

A 10-bit shift register is used to generate the pseudo-random sequence in a DS spread spectrum system. The chip duration is T_c = m, and the bit duration is T_b = N·T_c, where N is the length (period) of the m-sequence. The processing gain of the system is

A DS spread spectrum system transmits at a rate of 1 kbps in the presence of a tone jammer. The jammer power is 20 dB greater than the desired signal, and the required Eb/N0 to achieve satisfactory performance is 10 dB. If the jammer is a pulse jammer, then the pulse duty cycle that results in worst-case jamming is

An FH binary orthogonal FSK system employs an m=15 stage linear feedback shift register that generates an ML sequence. Each state of the shift register selects one of L non-overlapping frequency bands in the hopping pattern. The bit rate is 100 bits/s. The demodulator employs non-coherent detection.

Suppose the hop rate is increased to 2 hops/bit and the receiver uses square law combining the signal over two hops. The hopping bandwidth for this channel is
