Parallel port controls arbitrary-waveform generator - 06/13/02 EDN-Design
Ideas....You can use the parallel port of your PC and a few additional
components to generate a powerful, easy-to-use arbitrary-waveform generator.
By using a Visual Basic program with the circuit in Figure 1, you can
generate any waveform (for example, sinusoid, triangle, amplitudeor
frequency-modulated, or exponential decay].... EDN is migrating links. This

Precision Waveform Converter uses Sawtooth Wave - 03/01/96 EDN-Design
Ideas....The circuit in Figure 1 can convert almost any waveform into another by
coupling a sawtooth waveform with the reference inputs of a conventional bank of
comparators. This addition allows the circuit to control the discharge time of
CD more precisely. The circuit has numerous applications,.... EDN is migrating links.

Programmable oscillator uses digital potentiometers - 7-Mar-02 Issue of EDN
Digital potentiometers are versatile devices; you can use them in many filtering and
waveform-generation applications. This Design Idea describes an oscillator in
which setting the resistance of two digital potentiometers independently programs the
oscillation amplitude and frequency. Figure 1 shows a typical diode-stabilized Wien-bridge
oscillator that generates accurate sine waves fro.... [Design Idea by Alan Li, Analog
Devices, San Jose, CA] |

Programmable Ramp Generator has 14 Bit Linearity - 09/12/96 EDN-Design
Ideas.... This linear ramp generator uses a DAC, a transistor array, MOSFET switches,
and current-steering techniques to achieve 14-bit linearity (Figure 1). The output
current of IC1, a DAC-10, is a product of the digital code and the reference-current
input, where IO=(code/1024]×2IR. IR is.... EDN is migrating links. This link is not

Pulse Generator & Signal Tracer - Dual-purpose test-instrument Very simple
Circuitry,1.5 Volt Battery-operated (added 09/05) |
|
Pulse generator aids IC testing 09/01/09 Test & Measurement World: As ICs
increase in complexity and decrease in size, their pin counts drop or, at best, remain
constant. The result: a need for pin-saving measures like serial programming. In the
past, multiple pins might have been available for programming an IC’s current or
voltage limit, but today’s ICs often encode that limit as a set number of pulses on a
serial line. -- [Kevin Frick, Maxim Integrated Products, Sunnyvale, CA] |
|
Pulse generator has Low top side aberrations - 05/25/00 EDN-Design
Ideas....Impulse-response and rise-time testing often require a fast-rise-time source
with a high degree of pulse purity. These parameters are difficult to achieve
simultaneously, particularly at subnanosecond speeds. The circuit in Figure 1, derived
from oscilloscope.... [Design Idea by[Jim Williams, Linear Technology Corp, Milpitas,
CA] |

Pulse Generator Verifies Test Setups - 05/26/94 EDN-Design
Ideas....Verifying the rise-time limit of wideband test-equipment setups is a
difficult task. In particular, you must often know the "end-to-end" rise time of an
oscilloscope/probe combination to ensure measurement integrity. Fig1s circuit provides
an 800-psec pulse.... EDN is migrating links. This link is not verified. Google

Pulse Generator-High-Voltage - Voltage, by definition, is the electrical
pressure that causes current to flow through a conductor. When that pressure is
sufficiently high, a high voltage is produced. But how do we define high-voltage? Is
100, 1000, or 10,000 volts considered high voltage? When compared to 10 volts, they
all can be considered high voltage.…. [Rewritten by Tony van Roon (VA3AVR)] |

Pulse Stretcher Increases ECL Gate Gains - 01/20/94 EDN-Design
Ideas....stretches the output pulses of an ECL comparator by operating the ECL line
receivers with unusually large pulldown resistors to the -15V supply. The large load
resistance maximizes the gains of the emitter-follower output stages and speeds up the
rising edges.... [Design Idea by Nicholas J Bucska, PC Peripherals, Louisville, CO] |
|
Pulse Width Adjuster Reverses Servo Motor - 03/17/94 EDN-Design
Ideas....Typical remote-control systems and robotics applications use standard R/C
servos, which often require a reversal of the direction of rotation. Since varying the
input signal's pulse width between 1 and 2 msec controls the servo's output position,
a circuit that adjusts the pulse width.... EDN is migrating links. This link is not

Pulse Width Trimmer Outdoes One-shots - 03/03/97 EDN-Design Ideas....The
simple circuit in Figure 1a trims the trailing portion of a large-width input pulse to
a size as narrow as 10 nsec. The input to the circuit is an active-low TTL pulse
longer than 10 nsec or a continuous low level after a high-to-low transition. The
output is a fixed 10-nsec pulse,.... EDN is migrating links. This link is not

Pulsed Sensor Extends Battery Life - 01/01/98 EDN-Design
Ideas.... Activating the sensor circuit in Figure 1 for 1 sec every 30 minutes lowers
its 20-mA supply current to an average of 70 µA. For a battery comprising three AA
Duracells, this pulsed operation extends the battery's life to several years. The
sensor uses an optocoupler and an IR-emitting diode.... [Design Idea by Terry Millward,
