Are there any decent dip package mixer ic's? It's very difficult to find them. A simple mixer ic to mix 2 signals is all I need. I have seen 20 pin and 32+ pins. Anything out there that is simpler for the purpose of breadboarding?
I know that there are some products out there, but they run on bands that are common, such as 2.4ghz or 900mhz which I know will interfere significantly with other wireless devices in my house. I was thinking of using a frequency not heavily used in the 300-800MHz range to minimize interference...
I have a question regarding those pre-made wireless ic's that are ready to use that you buy in pairs (one is the transmitter unit and the other is a receiver unit). Now I want to use this in a project where I take a signal that is split from my cable television line and send this signal to the...
Many thanks on the links, now perhaps a physicist can enlighten me, can the sounds waves at 40KHZ on a range sensor penetrate walls if operating within operational range? Or would the sound waves always be bounced off walls or windows and not get through to the other side?
I have a question regarding ultrasonic sensors. Let's say for example I want to use a typical ultrasonic sensor, in this case let's say: http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=136653

I have a question about microcontrollers. Up until now in my university career I have only used microcontrollers that are already mounted on a circuit board that has pins already set up much like an IC. Now I am interested in going more in depth in this area. My question is are there any...
Determine the theoretical spectrum by determining the Fourier transofrm for the output x(t), in the problem given below.
x(t) = f(t)(g(t)
f(t) = cos(w_0*t), Frequency = 10 KHZ
g(t) = 20% duty cycle rectangular wave, pulse height = 1, baseline = 0, frequency = 100 KHZ
From what I know right...
Hello there,
if I have a impulse train as f(t) with a frequency of 100 khz, and cos(w_0*t) = g(t) with frequency of 10 khz, how do I go about determining the signal spectra, (i.e. harmonics n = 1,2,3...)? I determined the Fourier transform, but I get stuck as to what to do with it. :confused...
Another problem I can't figure out how to start.
Let S be the subspace of C[a,b] spanned by e^x , xe^x , (x^2)e^x . Let D be the differentiation operator of S. Find the matrix representing D with respect to [e^x, xe^x, (x^2)e^x ]
I really thank you guys for your help and patience with me.
I think I figured out my answer, and it all makes sense. You guys are awsome.:smile: :approve: :approve: :approve:
I just realized that the combination I created is one of a few different combinations, does that matter which combination I use? I still can't get an answer. Or rather, I still can't get the answer that matches the books. is my linear combination correct?
