How do you calculate ADC sampling rate?

How do you calculate ADC sampling rate?

For ADCs like Flash convertors and SAR, the sample rate for each channel can be calculated by dividing the specified sample rate by the number of channels.

What is sampling frequency in ADC?

Sampling frequency: it is the frequency at which the ADC samples the analogue signal (usually in number of samples per second (Hz)) Sampling period: the reciprocal of the sampling frequency, i.e., the interval between corresponding points on two successive sampling pulses of the sampling signal.

How does ADC increase sampling rate?

To increase the sampling rate of an ADC whose comparators are already running at maximum speed, the number of upper (coarse) and lower (fine) quantizer blocks must be extended. This can be achieved by implementing an N-bit, coarse ADC and two time-interleaved, N-bit, fine ADCs (Figure 2).

What is data rate in ADC?

analog input or sending out (DAC) an analog output. • Data rate is the rate of the digital output data from an ADC or digital input data rate. to a DAC.

What is the minimum sampling rate?

The minimum sampling rate is often called the Nyquist rate. For example, the minimum sampling rate for a telephone speech signal (assumed low-pass filtered at 4 kHz) should be 8 KHz (or 8000 samples per second), while the minimum sampling rate for an audio CD signal with frequencies up to 22 KHz should be 44KHz.

What is minimum sampling frequency?

What is oversampling ratio in ADC?

Oversampling Description As a general guideline, oversampling the ADC by a factor of four provides one additional bit of resolution, or a 6 dB increase in dynamic range. Increasing the oversampling ratio (OSR) results in overall reduced noise and the DR improvement due to oversampling is ΔDR = 10log10 (OSR) in dB.

What is RF Duc?

DUC stands for Digital Up Conversion and DDC stands for Digital Down Conversion. Both of these modules are used in Software Defined Radio based systems.

What is the resolution of a 12-bit ADC?

ADC has a resolution of one part in 4,096, where 212 = 4,096. Thus, a 12-bit ADC with a maximum input of 10 VDC can resolve the measurement into 10 VDC/4096 = 0.00244 VDC = 2.44 mV. Similarly, for the same 0 to 10 VDC range, a 16-bit ADC resolution is 10/216 = 10/65,536 = 0.153 mV.
