 | | The employment of a Feature Extraction Pre-Processor can be used to enhance a host Electronic Surveillance System’s Emitter Track and ID capabilities using observable intentional modulation on pulse (IMOP) unintentional modulation on pulse (UMOP) features. | | | Using the VHDL design code provided on this effort, custom higher gate density FPGAs or even more efficient ASICs could be used to achieve size reduction necessary for UAV ELINT applications. | | | Techniques employed in the development and integration of detection, measurement, and typing algorithms can be used to develop products to automate air traffic control operations, easing ATC operator burden and increase situational awareness. |

| | One such encoding technique is pulse code modulation (PCM), however, others may be used. | | | Display 70 may be a conventional radar scope, a dedicated CRT display, or other display. | | | Also, ATC computer 66 may also transmit such information to other aircraft in the area to allow such aircraft to be aware of other aircraft that are nearby. |

| | Differential pulse-code modulation (DPCM): Pulse-code modulation in which an analog signal is sampled and the difference between the actual value of each sample and its predicted value, derived from the previous sample or samples, is quantized and converted, by encoding, to a digital signal. | | | Adaptive differential pulse-code modulation (ADPCM): Differential pulse-code modulation (DPCM) in which the prediction algorithm is adjusted in accordance with specific characteristics of the input signal. | | | Pulse-code modulation (PCM): Modulation in which a signal is sampled, and the magnitude (with respect to a fixed reference) of each sample is quantized and digitized for transmission over a common transmission medium. |

| | Pohlmann (Ken) Principles of Digital Audio Summary |
| | Types of digital modulation include PWM pulse width modulation (pulses of variable width, uniform height), PPM pulse position modulation (pulses onset is variable), PAM pulse amplitude (pulses have variable amplitude, uniform timing and width), PNM pulse number (very narrow pulses firing at varible rate, uniform pulse height and width), and PCM pulse code modulation {p. | | | This EFM code is modulated to NRZ code (a pulse for each 1 in the bitstream) and this NRZ is converted to NRZI (in which there is a transition for each NRZ pulse) {p. | | | The EFM code is recovered from the radiofrequency RF signal from the photodiode by detecting the NRZI signal, and converting it to NRZ and thus to EFM. |

| | Pulse code modulation |
| | The pulse amplitude modulation pulses are then encoded into a binary code that is transmitted as a digital stream. | | | Pulse-code modulation (PCM) is similar to pulse-position modulation (PPM) in that the received information is not determined by the shape of the pulse, but has the additional advantage that the precise location of the pulse is not important either. | | | In adaptive differential pulse-code modulation (ADPCM), the binary number that is transmitted is not the number that corresponds to the actual voltage level, but rather the difference between the current sample value and the last. |

| | pulse-code modulation |
| | In physics, a form of digital modulation in which microwaves or light waves (the carrier waves) are switched on and off in pulses of varying length according to a binary code. | | | The amplitude, duration, and timing of a series of pulses are controlled in pulse-code modulation, which is relatively simple for digital data already in binary code. | | | Morse code is a very simple example of pulse-code modulation. |

| | Then to transmit code #1 followed by code #2, a modulation pulse would be placed at 40 consecutive zero crossings (code #1), and then at least one zero crossing would be skipped (missing pulse), and then a modulation pulse would be placed at 41 consecutive zero crossings (code #2). | | | This means that the transmitter will delay (in increments of 8.33 milliseconds) its transmission until it detects a zero crossing that contains no pulse, thereby insuring that no extra pulse is added to the start of its code. | | | Referring again to the 3-phase waveshapes, when the Transmitter is on the 1st phase, it places its pulses at the zero crossings of that phase, and the 3 Phase Coupler/Repeater will repeater the exact pulse count at the zero crossings of the other two phases (with the appropriate delay). |
