BatteryPowered Sine Generator Covers 100 Hz To 10
kHz : 05/27/02 Electronic Design - Ideas for
Design / We needed a handheld, battery-powered
signal generator with a sine-wave output that was
continuously adjustable from 100 Hz to 10 kHz. For
such a wide frequency range, we selected a
function-generator type of oscillator, which
requires a... |

05/15/03 EDN-Design Ideas / The circuit of Figure 1
produces an accurate, variable-frequency sine wave
for use as a general-purpose reference signal. It
includes an eighth-order elliptic,
switched-capacitor lowpass filter, IC3, which uses a
100-kHz square-wave clock signal that
microcontroller IC2 generates. (Any other convenient
square-wave source is also acceptable... |

Low Frequency Sine Wave Generator: The two
circuits below illustrate generating low frequency
sine waves by shifting the phase of the signal
through an RC network so that oscillation occurs
where the total phase shift is360 degrees.

Programmable oscillator uses digital potentiometers:
03/07/2002 EDN - Design Ideas / 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... . |

The Wien bridge oscillator is reborn:
06/13/2002 EDN - Design Ideas / In 1940, William
Hewlett and David Packard launched a product from a
garage. The product was a Wien-bridge oscillator. It
consisted of a single-pole highpass filter in series
with a single-pole lowpass filter. To keep the gain
constant, the circuit used an incandescent pilot
light to provide AGC (automatic gain control) |

The Wien-bridge sine-wave oscillator uses a
light bulb to stabilize its amplitude. The circuit
doesn't have a light bulb; it sports several
enhancements that lower its distortion and generate
a test signal pure enough for testing modern op amps
and high-resolution A/D converters.
