Thanks for your reply. I was hoping it would work over larger distance 25-30 meters (similar to range of keyless entry of cars). If this can work, its for someone who has recently lost their hearing. There are all kinds of alerting and signaling systems available for the hearing impaired. They...

Hello, I have this old toy RC car and a pager and I am wondering if a small hack, using the two is possible or not. The pager doesn't work but its motor does. I want to make a new "pager" that vibrates when the car's remote is used. The car has a small reciever circuit (27MHz if that's of any...

Thanks for the pdf. Very useful though its taking a while to fully digest... I don't really have a "desired filter". I really just want to provide an (interactive) visualization, where the user picks a center frequency, chooses to cut or boost gain and then sets a pass band. Should be...

Thanks for the response. I have done complex arithmetic in college, but have never found a use for it since. I don't mind dusting out the cobwebs if it makes plotting the curve simpler. I am just not very sure where to start. As to the language, I would use C# or python. I have seen audio...
