µC makes inexpensive sine-wave generator - 12/17/98 Issue of EDN
You can use A/D converters or external, controllable oscillators to generate
sine waves from low-power, low-cost µCs. However, these methods add cost,
reduce reliability, increase circuit and software complexity, increase power
consumption, and increase overall size. Alternatively....Page includes
several designs. Scroll to find this one.... [Design Idea by Jorge

68HC11 Synthesizes Accurate Sine Wave - 09/02/96 EDN-Design Ideas....You can
use a 68HC11 and a 12-bit serial DAC (Figure 1) to generate accurate sine waves
without using floating-point arithmetic. Figure 2 shows a block diagram for this
sine-wave generator. You can easily analyze the generator's behavior by writing state
equations in the z domain. You can also write equations in the s domain. The location
of the two poles.... [Design Idea by Mika Maaspuro, Espoo, Finland] |

AF Generator - My generator can produce sine- and squarewaves with
frequencies between 1 Hz and 100 kHz and amplitudes ranging from zero to 1.55 Veff in
600 Ohms. Sinewave distortion is 0.1% or less between 20 Hz and 20 kHz, somewhat
greater outside this region. The output voltage …(electroninc design added 04/05/06)

Audio LED VU meter - Audio level meter circuits are fairly often requested.
The circuit was designed to work with an audio power amplifier which operated off
+18v-0v-18v power rails. The actual voltage used is not too critical except that the
feedback is referred to the LED chain which itself is anchored to a +12v rail, hence
the separate stabilizer for this. It has one large advantage over most of the LED
chips available - all the LEDs are in series so it only draws 20mA irrespective of the
number of LEDs illuminated....[4QD-TEC: Electronics Circuits Reference Archive]

Compensation Extends Oscillator's Range - 12/05/96 EDN-Design Ideas....A
simple technique provides phase compensation for the oscillator in Figure 1a. In this
circuit, a tungsten lamp regulates the amplitude of a crystal bridge oscillator.
This type of oscillator produces a very low-distortion output at a very stable
frequency. The op amp must have a negligible phase shift at the operating frequency,
which.... [Design Idea by Israel Schleicher, Green Spin, Bakersfield, CA] |
