Ok awesome, did not know that about the power line. I'm working on those fixes right now. Any way you could answer some of my questions about the antenna also?
How can I found out more about this stuff without asking people? Any good books that are not crammed purely intense mathematical...
Here is the bottom of the board:
Ok I can rearrange the balun circuit, I was just trying to arrange them to keep the traces between them as short as possible.
You are correct the wider trace was supposed to be the feed line (73 mil) which yes you are correct I was planning on using 63 mil...
I have designed a small transmitter (and receiver) that will use a Microchip MRF49XA transceiver chip. I have layed out both boards but on the transmitter board (remote control) I am having trouble selecting an antenna. The board is very compact as you can see in the picture below. I was...
Really? That sucks. I don't know about everybody else but I use different sizes based on the size of the component. If it's a huge component I use large text.
When I am creating a custom PCB footprint in altium how do I specifiy a position and size for the reference designator when I create the component. I know the program will automatically put one when I place it on the board but I want to be able to define ahead of time a position and size. How do...
Yeah I knew about the net label thing but was wondering about finding out without doing that. The answer is you can just drag your mouse over the wire and a little popup comes up showing the name of the net. Thanks.
I am using altium 10.391 (2011) and am still pretty new to it but am practicing with a small design. I was wondering, how do I view the net names of the wires on my schematic page? Like if I want to know the name of a specific wire how do I do this? I know they are named based on where they are...
Ok yes, because the capacitor ideally allows infinite current at startup right, so I just calculate it as if it wasn't there. But like you said it will briefly carry around 600 watts (because of the surge), so should I size the resistor based on the constant current and then bump it up a tad (so...
I have designed the following transformerless power supply (based on many sources around) but I'm not sure how to calculate the proper size of the resistor to limit inrush current. Will a 1W 47 ohm resistor be sufficient? This is the zener diode I want to use...
You mean the whole count if statement?

Cool that worked. Why is it that it has to be within that same statement? Is it because of how it sequentially evaluates each statement? Sorry I'm new to VHDL and I'm still getting used to the hardware description aspect of it and...
I am using a Xilinx FPGA on a digilent FPGA demo board. Using Xilinx's ISE software I have written the following code:
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use ieee.std_logic_arith.all;
use ieee.std_logic_signed.all;
entity clock is
PORT(CLK : IN STD_LOGIC;
RESET : IN STD_LOGIC...
But how does it help us in analysis? What is the advantage of using imaginary numbers. Like with a DTFT instead of a complex exponential/sinusoid why couldn't we use a strictly real sinusoid?
I'm in a discrete time signals class at my University and we talk about signals all the time that have imaginary portions. But I don't understand what this actually means in terms of a "real" life signal. I understand the relation to a vector spinning about the imaginary and real axis but what...
