First to check the transmitter circuit, the address pins are yours you can give them any value you want then there are data pins then comes the TEN which is transmit enable and is enable low so you have to make it zero every time you transmit something, generally problem comes here only with the...
I have simulated a circuit in PSICE with same values of components and it showed the same synchronized output.
here's the schematic
as you can see the message signal is -0.5V to 0.5V with a time period of 1ms and the marker is the output of the circuit and the output is as shown
ohk ill try this if it works..
at the receiver the same circuit with same values synchronous to the transmitter will be deducted from the received message,and the left over is the message signal with channel noise....

help me plsss...
that's what I am asking the circuit is very sensitive to the values of resistor between those capacitors
like in my case there is a range or R from 1.66k to 1.86k till it shows chaotic behavior otherwise not, and the taken conditions are giving me a frequency as mentioned above bot I need a...
I recently simulated chua's double scroll attractor in PSPICE with L=18mH C1=100nF and C2=10nF
which gave the output as
but FFT showed that the output has a frequency range of 2KHz to 3KHz
I want to use the chaos generated in secure communication so I could modulate my message signal over...
HC-SR 04 is an ultrasonic sensor but its range is upto 4 m
here's the data sheet
http://users.ece.utexas.edu/~valvano/Datasheets/HCSR04b.pdf
and to ans your question how can you use it in your work here's an example project

There are Ultrasonic distance measurement sensor which costs around INR 950
or a bit inexpensive way is to use a IR sensor which has a tx and a rx and gives a voltage level according to the distance from where the ray is been reflected back.
but the IR sensor is not that effective it works for a...
Here's a book for 8051 microcontroller. This book is good and have detailed explanation for everything
