The green analog curve is discretized in time and level resulting in the red points.
The smallest difference in level is called delta Δ or LSB (least significant bit).
The smallest difference in time is called sampling time (ts).
The smallest difference in level is called delta Δ or LSB (least significant bit).
The smallest difference in time is called sampling time (ts).
Data converter application: software defined radio SDR
A tuneable filter provides a limited bandwidth to an ADC.
The radio protocol (WiFi, Bluetooth, FM, AM, digital-TV,LTE)
is realized in the digital signal processing block.
Data converter application: Mobile phone

Filters Number of data converters: HSDP, LTE, UMTS, WLAN, bluetooth motion, pressure, proximity sensor speaker, microphone display control |
Digital to analog converter metric
|
\[ \Delta = \frac{V_{ref}}{2^N} \]
\[ N = log_2 \frac{V_{ref}}{\Delta} = ld \frac{V_{ref}}{\Delta} \]
\[ V_{max} = V_{ref}- \Delta \]
|
\[ V_O = V_{ref} \sum_{i=0}^{N-1} \frac{D_{i}}{2^{N-i}} \] \[ V_O = \Delta \sum_{i=0}^{N-1} D_{i} \cdot 2^{i} \]
Attention: Vref, Vmax, VFS
Analog devices Data Converter book sometimes states VFS = Vref
Baker (Equation 28.8) and Texas Instruments Understanding Data converters define VFSR = Vmax
In some circuit architectures Vref = Vmax
Watch out and act accordingly.
