Given is the measured bit sequence of an RS232 serial transmission:

Which character (letter) is received here?

You know the ASCII code from IT knowledge:

Please convert the following sequence into a text. Upper/lowercase is important and no extra spaces or other characters please.

0x43 0x6F 0x64 0x65

You know the ASCII code from IT knowledge:

Please convert the following bit sequence into a text. The bit order is LSB first (like in RS232). Upper/lowercase is important and no extra spaces or other characters please.

01000010 10011110 00101110 10100110

A base band signal of maximum bandwidth B=24000 Hz needs which minimum sampling rate? Hz.

An A/D converter with 8 bits is used with an input signal of (relative) power level K=-20 dB.

Calculate the SNR value: dB.

Hint: Assuming linear region and no clipping.

An A/D converter with 12 and a maximum voltage swing of Vpp=5 has which voltage step size? Volts.

Hint: Fractional numbers can be written as 0.001 or 1e-3.

An A/D converter (ADC) with 5 bits can represent different values.

A base band signal of maximum bandwidth B=100000 Hz needs which minimum sampling rate? Hz.

An A/D converter (ADC) with a resolution of 128 steps needs how many bits?
