    How to get two Sweep and Repeat Generators in sync.

    What is the best way to make a sign wave shift frequency downward only about 10 Hertz, then repeat every .2 seconds. The initial frequency 3000 Hz. There will be 2 generators sweeping, both will be in sync (repeat at the same time). See attachment for drawing.

    Microwave Oven Door Perimeter Seal

    On the microwave oven door itself, on the inside of the door around the perimeter there are a number of cavities. You must pop off a removable plastic cover inside the door to see them. The cavities are formed from a bunch of bent tabs 3/4 inch wide, 3/4 inch deep, and are spaced every 3/8...

    Double Sheet Detector

    I was just considering attenuation of the sonic signal to determine if 2 sheets were present then less sound would get through.

    Double Sheet Detector

    I am new here. I am in need of a circuit to detect and warn me when 2 sheets of paper board (about 2 credit card thickness) and only 1 sheet is present. I know a piezo transducer and receiver at 40 kHz is the correct frequency so I ordered the TCT40-16R/T piezo tranducer receiver pair. The...

    Combining Two Waves Experiment

    Yes I've heard this before being infulenced. Both generators are old tectronics tube type but are very well built and stable.

    Combining Two Waves Experiment

    This is my first post here so I hope everything is ok. - I read the rules. Do rf sign waves have a small attraction for each other when they are near the same frequency? I thought that electronics men might know why this happens. My experiment shows that they have some attraction for another...
