The door bell circuit
Figure 1 illustrates an economical and straightforward Gate Alarm designed to operate using a small universal AC-DC power supply. IC1a functions as a fast oscillator, while IC1b serves as a slow oscillator. These two oscillators are integrated through IC1c to...
AudioWave 2.0
With AudioWave 2.0 your soundcard becomes a comfortable LF-signal-generator, which produces signals from 1Hz to 20 kHz with a resolution of 1 Hz. Phase shift between left and right channel is adjustable from 180° to +180° and an attenuator can...
High drive oscillator-flasher
The driver in the package is configured as a Schmitt trigger oscillator (A), utilizing resistors R1 and R2 to create hysteresis. The inverting feedback timing components consist of resistor R3 and capacitor C, while resistor R4 serves as the pull-down...
Oscillator without a crystal
Is it possible to build an oscillator (VCO or not) without using a crystal? I built a Pixie II with a borrowed crystal, which I have since returned, and now I am inquiring about the feasibility of constructing an oscillator...
Test Signal Generator
This signal generator uses a three channel DAC to generate Composite video signal (CVBS) and S video signal (Y/C separated) at the same time, left one channel is not used in NTSC format. It is assigned for one of the...
The Multi-purpose signal generator circuit
The multi-purpose signal generator circuit consists of integrated circuit oscillators and frequency dividers. It generates square waves ranging from high frequencies to sub-audio frequencies and also produces a frequency standard in the VHF range. The alternative oscillator section feeds the...
450 800Hz signal generator circuit diagram
The 450/800Hz oscillation circuit depicted in the figure utilizes transformer coupling. The frequency conversion is achieved by varying the inductance through a variable filter tap (T1). When the switch control signal (S) is set to position 1, the oscillator circuit...
RF Signal Generator
This signal generator is designed for the realignment of radio receivers. It is an economical and straightforward unit, adequate for its intended application. However, the output is not a pure sine wave, which may limit its suitability for more precise...
Last-cycle-completing-gated-oscillator
Regenerative feedback at capacitor C allows the oscillator to complete its timing cycle instead of shutting off immediately. The integrated circuit (IC) used was a CD4011AE, although an equivalent IC will also function.
The described circuit utilizes regenerative feedback to enhance...
