Be sure to keep track of the result value and the remainder for each one. Here we go:. Each place has a value, and you add up all the digits! This time, though, each place is a power of Honestly, for hexadecimal values longer than two digits, I always use a calculator or some other tool. That is an easy number to remember. For those paying attention, you might recognize that 0 - are also the values that can be shown in 8 binary digits — or one byte! This is useful because things like CSS commonly use hex digits when referring to values in that range. So we know that BADA55 is a color with quite a bit of green, medium-high amounts of red, and not a whole lot of blue.

Similarly, the process for converting decimal numbers to hexadecimal is the same as converting binary to decimal. Either of the binary methods can be used subtraction or division. However you want to do it! The nice thing about hexadecimal and binary is that 16 is a multiple of 2.

When converting hex to binary, you can essentially interchange each hex digit for 4 digits of binary and vice versa. Therefore, our frequency spectrum will have the following equation:.

We remember from the Signals and Systems book that convolution of a signal with an impulse is that signal centered where the impulse was centered. Therefore, we know now that the frequency domain shape of this curve is a sinc wave centered at the carrier frequency. In Frequency Shift Keying FSK , we can logically assume that the parameter that we will be changing is the frequency of the sine wave. FSK is unique among the different keying methods in that data is never transmitted at the carrier frequency, but is instead transmitted at a certain offset from the carrier frequency.

Using the same logic that we used above, the fourier representations of these waves will be respectively :. With one sinc wave centered at the first frequency, and one sinc wave centered at the second frequency. Notice that A1 and A0 are the half-square waves associated with the 1s and the 0s, respectively. These will be described later. PSK systems are slightly different then ASK and FSK systems, and because of this difference, we can exploit an interesting little trick of trigonometry. PSK is when we vary the phase angle of the wave to transmit different bits.

For instance:.
