Binary Code Electrical Signals
With BogusBus, our signals were very simple and straightforward: each signal wire (1 through 5) carried a single bit of digital data, 0 Volts representing “off” and 24 Volts DC representing “on.” Because all the bits arrived at their destination simultaneously, we would call BogusBus a parallel network technology. If we were to improve the performance of BogusBus by adding binary encoding (to the transmitter end) and decoding (to the receiver end), so that more steps of resolution were available with fewer wires, it would still be a parallel network. If, however, we were to add a parallel-to-serial converter at the transmitter end and a serial-to-parallel converter at the receiver end, we would have something quite different. It is primarily with the use of serial technology that we are forced to invent clever ways to transmit data bits.

Lets have a look at how they work. Binary binary code electrical signals digits can be grouped together into bytes Apr 17, 2016 WinWin Signals is a new binary options product being brought to our. (TCO 1) In NRZ, line encoding is a binary code where 1s are represented by _____. (Points: 5) the absence of a signal the presence or level of a signal a circular, sinusoidal signal line block coding.4. (TCO 1) In 10BASE-T systems, the distance limit of 100 meters for a horizontal cable is due to _____. Computers use electrical signals that are on or off, so they have to see everything as a series of binary. This data is represented as a sequence of 1s and 0s (on and off).
Because serial data requires us to send all data bits through the same wiring channel from transmitter to receiver, it necessitates a potentially high frequency signal on the network wiring. Consider the following illustration: a modified BogusBus system is communicating digital data in parallel, binary-encoded form. Instead of 5 discrete bits like the original BogusBus, we’re sending 8 bits from transmitter to receiver. The A/D converter on the transmitter side generates a new output every second.

That makes for 8 bits per second of data being sent to the receiver. For the sake of illustration, let’s say that the transmitter is bouncing between an output of 10101010 and 10101011 every update (once per second): Since only the least significant bit (Bit 1) is changing, the frequency on that wire (to ground) is only 1/2 Hertz.

In fact, no matter what numbers are being generated by the A/D converter between updates, the frequency on any wire in this modified BogusBus network cannot exceed 1/2 Hertz, because that’s how fast the updates its digital output. 1/2 Hertz is pretty slow, and should present no problems for our network wiring. On the other hand, if we used an 8-bit serial network, all data bits must appear on the single channel in sequence. And these bits must be output by the transmitter within the 1-second window of time between A/D converter updates. Therefore, the alternating digital output of 10101010 and 10101011 (once per second) would look something like this: The frequency of our BogusBus signal is now approximately 4 Hertz instead of 1/2 Hertz, an eightfold increase!

While 4 Hertz is still fairly slow, and does not constitute an engineering problem, you should be able to appreciate what might happen if we were transmitting 32 or 64 bits of data per update, along with the other bits necessary for parity checking and signal synchronization, at an update rate of thousands of times per second! Serial data network frequencies start to enter the radio range, and simple wires begin to act as antennas, pairs of wires as, with all their associated quirks due to inductive and capacitive reactances. What is worse, the signals that we’re trying to communicate along a serial network are of a square-wave shape, being binary bits of information. Are peculiar things, being mathematically equivalent to an infinite series of sine waves of diminishing amplitude and increasing frequency. A simple square wave at 10 kHz is actually “seen” by the capacitance and inductance of the network as a series of multiple sine-wave frequencies which extend into the hundreds of kHz at significant amplitudes. What we receive at the other end of a long 2-conductor network won’t look like a clean square wave anymore, even under the best of conditions!
