Opamp Function Generator

Documentation in Acrobat format (K23)

cps23.jpg
Good value-for money & simple circuit to generate square, (pseudo) sine and triangle waveforms in the audio range. Uses quad opamp LM348.

You do not need a lot of money to have access to square, triangle or sine waves in the audio range. This simple kit uses four operational amplifiers (opamps) to deliver these waveforms in the 6 Hz to 7000 Hz range. The sine wave is a pseudo sine wave produced by a very simple wave shaping circuit.(CPS23)

Square Wave Oscillator LN/NE555 (inc box
 
Simple circuit to generate square waves of approximately 1Hz 10Hz 100Hz 1KHz 10KHz & 100KHz. A square wave generator is one of those pieces of equipment that has many uses in the workshop yet few hobbyists actually have. This simple kit, based on the popular 555 timer IC, generates six preset frequencies from 1Hz to 100khz. It has an operating voltage range of 5 to 18VDC and even provides visual indication of the output. The kit is constructed on a single-sided printed circuit board (PCB). The PCB size: is 78 x 50mm (3.1" x 2") and will mount on a small plastic 'Jiffy' box. (CPS111)
