2. Impedance matching - Wikipedia

   en.wikipedia.org/wiki/Impedance_matching

   If Z/Z 0 is inside the 1+jx circle on the Smith chart (i.e. if Re(Z/Z 0)>1), network (a) can be used; otherwise network (b) can be used. [2] A simple electrical impedance-matching network requires one capacitor and one inductor. In the figure to the right, R 1 > R 2, however, either R 1 or R 2 may be the source and the other the load. One of X ...

3. Correlated double sampling - Wikipedia

   en.wikipedia.org/wiki/Correlated_double_sampling

   When used in imagers, correlated double sampling is a noise reduction technique in which the reference voltage of the pixel (i.e., the pixel’s voltage after it is reset) is subtracted from the signal voltage of the pixel (i.e., the pixel’s voltage at the end of integration) at the end of each integration period, to cancel kTC noise (the ...

4. Video modulation - Wikipedia

   en.wikipedia.org/wiki/Video_modulation

   Video signals are usually encoded into binary digit (0, 1) or seven digit pulse-code modulation (PCM), which is a method used to digitally represent original video signal. . The video signal converted to binary digit PCM at the point of origin can be then transmitted over existing telephone cable or wire directly to the destination

5. Gain (electronics) - Wikipedia

   en.wikipedia.org/wiki/Gain_(electronics)

   Graph of the input () (blue) and output voltage () (red) of an ideal linear amplifier with a voltage gain of 3 with an arbitrary input signal. At any instant the output voltage is three times the input voltage.

6. Analog television - Wikipedia

   en.wikipedia.org/wiki/Analog_television

   The audio signal goes to a 4.5 MHz amplifier. This amplifier prepares the signal for the 4.5 MHz detector. It then goes through a 4.5 MHz IF transformer to the detector. In television, there are 2 ways of detecting FM signals. One way is by the ratio detector. This is simple but very hard to align. The next is a relatively simple detector.

7. Signal conditioning - Wikipedia

   en.wikipedia.org/wiki/Signal_conditioning

   In electronics and signal processing, signal conditioning is the manipulation of an analog signal in such a way that it meets the requirements of the next stage for further processing. In an analog-to-digital converter (ADC) application, signal conditioning includes voltage or current limiting and anti-aliasing filtering.

8. Sample and hold - Wikipedia

   en.wikipedia.org/wiki/Sample_and_hold

   A typical sample and hold circuit stores electric charge in a capacitor and contains at least one switching device such as a FET (field effect transistor) switch and normally one operational amplifier. [2] To sample the input signal, the switch connects the capacitor to the output of a buffer amplifier. The buffer amplifier charges or ...

9. Programmable-gain amplifier - Wikipedia

   en.wikipedia.org/wiki/Programmable-gain_amplifier

   A programmable-gain amplifier (PGA) is an electronic amplifier (typically based on an operational amplifier) whose gain can be controlled by external digital or analog signals. The gain can be set from less than 1 V/V to over 100 V/V. [ 1 ] Examples for the external digital signals can be SPI , I²C while the latest PGAs can also be programmed ...
