Pyle makes some excellent quality outdoor wireless speakers. However many people have faced issues with Bluetooth not working. In this post we cover different problems and how to solve them. …
This tool converts from dBm (dB-milliwatt) to dBV (dB-Volt). Calculator Note: ? dBV to dBm Formula dBV = dBm + 10*Log10(Z) – 30 where Z is the impedance Background What …
dBm is the power level in dB referenced to 1 milliwatt. It is an absolute quantity that can be computed from Watt for instance. dBc stands for decibels relative to …
This tool calculates Effective Number of Bits (ENOB) in an Analog-to-digital converter (ADC). It uses the dB value of Signal Noise and Distortion (SINAD) and the formula: ENOBbits = (SINADdB …
This calculator gives the turns ratio of an RF transformer. Enter the input and output impedance. Formula Np/Ns = √(Zp/Zs) where Background What is an RF Transformer? An RF transformer …
This calculator finds the resistor value to be used with an LED and a +5 Volt supply. It also provides the power dissipation in the resistor – an important number …
The Arduino [1] Input/Output (I/O) pins can be used to control an LED and make it blink. It does this, by turning the output pin on and off. Arduino Resistor …
This calculator finds the resistor value to be used with an LED and a +12 Volt supply. It also provides the power dissipation in the resistor – an important number …
A current limiting resistor is used in series with a Light Emitting Diode (LED). In this post we will explain why we need this resistor. LED Current and Voltage Specifications …
Use this tool to calculate the equivalent impedance of any number of resistors in parallel, the voltage drop across each and the total current. There are two configurations considered in …
