I’ve been searching the internet for DC powered sine wave generators. I’ve seen many different types, but have had trouble keeping track of the advantages of each type. Could someone tell me what type of generator would be ideal for generating a regular wave that has a wavelength of about 1 foot? I’d need to know what parts of the generator need to be adjusted to change the amplitude (maybe just by adding a resistor by the output) and wavelength (to as short as about 1/8 of a foot). Also, the generator needs to be able to be driven by about 3 volts (less than 3.3 volts). Ground is usually negative, right? Assuming ground is negative, I need for the output of the generator to connect to the positive side of the power source. Thank you.
