  • Nonuniform pulse code modulation encoder using double polysilicon technology
    The logic to drive this array was realized in TTL and consists of about 170 gates, indicating that a total encoder can easily be integrated on a 2.5 X 2.5 mm2 total chip which leaves room enough to inte- grate …
    Additionally, these chips have up to a 4 x interpolation done on the chip itself, allowing for 5 Jim position resolution, while still outputting two TTL digital signals. This meant that position could be calculated using standard quadrature encoder hardware or logic .
  • A 30-MHz trellis codec chip for partial-response channels
    As mentioned previously, the encoder , detector, and decoder functions were implemented on the chip . The interleav- ing, deinterleaving, serial-to-parallel conversion, and parallel-to-serial conversion were implemented using off-the-shelf fast TTL logic .
  • Digital Monitor
    Recent advances in large scale integration (LSI) techniques, however, have resulted in the develop- ment of a monolithic 8 -bit, all- parallel encoder which operates at a reasonable power level though requiring additional off - chip circuitry to make it a complete A/D … In TTL , the logic time skew depends upon the direction of the transition.
  • Fast Serial Link Using Optical Fibers
    … interface chips - the 68450 Direct Memory Access controller and the 68230 Parallel Interface chip that actualy handle … The serial encoder translates parallel data from the interface into a single data stream/ with embedded clocking … The optical transmitter converts the data stream into a stream of near infrared (870 nm) photons that are received by the optical receiver (AT&T 1350A) for conversion back to a TTL - compatible logic stream.
  • Embedded displacement measuring device based on error separating technique of multi-circle overlapping three-probe method
    … composed of 3 BCD decade counters, which is used to gain the number of the TTL level. 10-to-4 line priority encoder chips which can transform decimal number into binary number are allowed to set the output values when the special input port has a high level(e.g. 4-A will output a high level while 4 … The output port of 74160 and 74147 are connected by a series of logic gate in order …
  • OTTER: The design and development of an intelligent underwater robot
    ASICs arc programmable logic devices that can implement the logic from hundreds of stan- dard integrated circuits in one user-programmable chip . One can submit a digital-circuit diagram, boolean-logic equations, basic TTL circuits created with a graphical … For control of the actuator, the Altera is used to con- vert the encoder signals from the …

  • Implementing Low Cost Solutions To Fill The Need For Quality Film Digitization
    … then applied as a pair of clocking signals to a bank of four ( TTL ) 74192 Binary Coded … The up/down feature of the 74192 chip used the logic of the rotation direction sensing stage to enable an up or down count, as appropriate, thereby incrementing and decrementing the cursor coordinate value in concert with the movement of the cross-hairs. Optical Shaft Encoder Joystick Left .
  • Application of DSP Controller on X–Y Table Servo Control
    A single chip microcontroller requires not only enough memory, but also a sufficient number of peripheral devices … This DSP servo control system includes an RS232 interface, a PWM output interface, and A/D and D/A converter interfaces, encoder and decoder interfaces and interfaces for external SRAM and EPM7064 logic ICs. … EPROM pro- grammable logic device (EPLD) and two PALs are chosen instead of TTL logic ICs to …
