The excitation is a 1-V peak

Gaussian pulse for all time-domain results presented in the following.

Gaussian pulse shape of the reflected signal.

In this case, we study the process for short fiber lengths where the efficiency of the process is high for the nonlinearity parameter values of R = 0.6 (

Gaussian pulse) and R = 0.4 (secant-hyperbolic pulse).

In Figure 10(a), both the input signals "A" and "C" are in binary state "0" whereas the input "B" is in binary state "1," and these are represented by corresponding

Gaussian pulses. In this condition, according to the simulation results, the sum of the input signals is in binary state "1" and thus this is represented by the

Gaussian pulse of wavelength 1557 nm and as the carry is in binary state "0," this is represented by the

Gaussian pulse of wavelength 1552 nm.

If the incident pulse is assumed to be

Gaussian pulse, the reflected group delay of the

Typical excitation signals used to determine the suitability of wide-band antennas to transmit pulsed signals are those based on the higher order derivative of the

Gaussian pulse. In this context, the antenna excitation signal has been selected to be the fifth derivative of the

Gaussian pulseAfter 6 [[tau].sub.inv] delay, delay between main clock and (De_Clk), the NMOS [M.sub.1] and [M.sub.2] turn on and discharge the node Pulse_O/P to ground so the

Gaussian pulse is designed.

The

Gaussian pulse shape used is described as in equation (1),

First consider the in-phase hybrid mechanism when an input

The transmitted signal is a

Gaussian pulse with a bandwidth of 5 GHz and its shape in the time domain is shown in Figure 3.

When the distance between nodes is 1500 mm without any obstacles in the indoor space, the main lobe of impulse response was distorted like a third order

Gaussian pulse, where the second wave troughs amplitude was larger than the first trough.
