ADC_Midterm_Notes

Relationship between transmission rates bandwith $$ = f_B $$ Binary data rate $$ = R_s = \frac{1}{T_s} $$ Roll off factor $$ f_B = \frac{1+\alpha}{2*T_s} $$ trade-off: An increase in a increase the required bandwidth but decrease the ISI, and vice versa. Sample signal and ideal low-pass filter $$ Example: \newline m(t) = 6cos(8,000\pi t) + 2cos(20,000\pi t) $$ Draw the portion of the amplitude of… Sample rate $$ = f_s > 2 * Highest \space Frequency \space component $$

UE5 Setup on MAC

Mac is not a recommended platform to develop Unreal Engine Project. Several things need to be noticed: Do not update your Mac to the latest macOS Ventura 13.0, as the Xcode will be incompatible. Do not use the latest Xcode 14, as the Unreal Engine only support Xcode 13.0, and Do not forget to turn off the update automatically.

Apm Conpile Debug

Build APM from source code on MAC Book M1 Pro and explore the possible debug(embedded) methods. Build waf is a special tool to organize the framework which means it is not quite common. the config script is written in python and seems can only generate .elf file for some specific boards like ESP32… Compile process become smoothly after I use a reliable but expensive proxy. Debug GDB on m1 mac is not supported till now, but lldb is available.
