2.A music signal with bandwidth Bx=20kHz has to be converted through an analog-to-digital converter with resolution 16 bit (this is the number of bits used to represent each real sample extracted from the analog waveform). The sampling frequency chosen is the least required to satisfy the sampling theorem. The stream of bits is transmitted digitally, one bit at the time, through a binary antipodal modulator. It is known that the probabilities of the bits emitted are p1=0.5 and p0=0.5. If the power spectral density of the Additive Gaussian Noise is No/2 with No=10-4 W/Hz, find the amplitude A of the modulator pulses that is required to achieve a bit error probability of 10^-5

Analog to Digital Converters

The analog-to-digital converter (ADC) allows circuits controlled by microprocessors, Arduinos, Raspberry Pi, and various reasonable digital circuits to be connected to the real world. In the real world, analog signals have a continuous stream of information from a variety of sources and sensors capable of measuring sound, light, temperature, or movement, in addition to the many digital systems that interact with their environment by measuring analog signals from those transducers.
