| 2011-07-10 | FranklinBlunt | Helpful for basic info but may I suggest two other blocks: Input/Output and Antenna. The I/O is implied with keypad, microphone, and such but what about the USB or other interface connections? Touch-screen is getting a bit more complex and even gets involved with the display so that can be developed another way beyond the basics. Antenna is definitely needed as a seperate block. A much overlooked component that is seemingly taken for granted. The design innovations and tuning methods were great advancements essential to the multi-function devices we have today. |
