Simulated Results And Analysis Of A Ver Of The System

SNR = Pout/Nout =0.005/ (4.5x10^-6) = 1.11 x 10^3 = SNR dB = 10log (1.11x10^3) SNR = 30dB

Next, you will add the AND and OR gates necessary to complete the circuit equations you derived in the lab report, part 1 section. The output F for the canonical SOP circuit should be shown on LEDG[0]. The output G for the canonical POS circuit should be connected to LEDG[1].

P is the reflectance proportion of EMR, M is the outgoing reflectance and E is the incoming reflectance. So in order to find the reflectance we are dividing the outgoing (M) reflectance to the incoming reflectance (E).

The programmed algorithm is shown in Figure 6.The program was developed using LabVIEW System design software. The entire experimental set-up is shown in Figure 7.

The stream of complex numbers is rearranged so that the pilots can be inserted. In each OFDM symbol, four pilot signals are inserted in order to make the coherent detection robust against frequency offsets and phase noise. The pilots are BPSK modulated by a pseudo binary sequence to prevent the generation of spectral lines [18]. A zero padded block adds zeros, in the right places, to adjust the IFFT bin size to length N. Selector block rearranges the sub-carriers so that real signal output can be generated. The IFFT block then computes the Inverse Fast Fourier Transform (IFFT) of length N, where, for ease of implementation, N is a power of

Inter symbol interference (ISI) is avoided by assuming the duration of cyclic long enough and furthermore the channel is assumed to be stationary within one symbol period ( h(k)=hr ).

In order to calculate the PSRR of the LDO, sine wave with 100mv amplitude is added to power supply to simulate noise of power supply. The PSRR of the proposed LDO is analyzed in the range of 10KHz to 10MHz and the simulation results are shown in Fig. 14. As it is shown, LDO works properly from 10KHz to 2.4MHz because after that Vout amplitude will become more than 10mV , so it cannot be neglected in compare with input sine wave which is 100mV. The proposed excessive current extraction (ECE) technique results in high frequency PSR of -88.69dB at 1MHz frequency. So, we can see the improvement of -48 dB and -13.69dB at 1MHz in compare with cap-less LDO without and with PSRR enhancer, respectively [14]. The LDO was

these subcarriers to a higher frequency band. Except for a multiplying constant (1=N), the above

Using the propagation of error formula, theoretical uncertainty of the unknown resistor RX can be calculated as,

The comparison of above three algorithms for 8, 16 and 32 bit operands with corresponding voltage and frequency are tabulated in table I

If we can get Broadcom PEX8749 driving strength capability. The SI simulation results will more accurate.

RECEIVER SECTION:- This section is worked as a Flip-flop (Bistable). IC-3 is decade counter, its Pin No.14 is input and Pin No. 2 output. The output of frequency detector stage is used, via a flip-flop, to switch ‘ON’ or switch ‘OFF’ a LED alternately. The receiver uses infrared modules IR-signal from the transmitter is sensed by the sensor through and its output PIN 1 goes low and switched LED. IC-3 is worked on clock pulse which receives to infrared modules at Pin No. 14. Its output at Pin No 2 throughes high.

The field of communications is one in which the technologies are changing on an almost daily basis. Numerous different technologies have been pursued over the past few years; each designed to essentially accomplish several basic purposes in terms of community service. Three of the most actively pursued application include interactive distance learning, video conferencing, and entertainment. While it is the first two, video conferencing and interactive distance learning, which would serve to the best advantage in terms of education and business; it is the last, entertainment which has the most appeal to the largest number of people. The application of various communications applications in
