Data Transmission: A data transmission system can be described simply in terms of three components, the transmitter (also called the source), the transmission path (usually referred to as the channel,…
DA Converter Working Principle: The resistive divider or ladder can be used as the basis for a DA Converter Working Principle. It is in the resistive network that the actual…
Variable Resistor Network: Variable Resistor Network - The basic problem in converting a digital signal into an equivalent analog signal is to change the n digital voltage levels into one…
Block Diagram of a Digital Filtering Processor: The implementation of any digital filtering consists of a series of multiplications of samples of the input and/or output signals by constants, and…
IIR Digital Filter Design Methods: IIR Digital Filter Design Methods - Fettveis first suggested the use of one port reflection coefficients for the transÂfer of analog filter properties from the…
Color Bar Generator: The composite video signal at the output of a video detector consists of luminance Y signals, the chrominance signal, the color burst, sync pulses and blanking pulses.…
Video Test Pattern Generator: A pattern generator provides video signals directly, and with RF modulation, on standard TV channels for alignment, testing and servicing of TV receivers. The output signal…
Marker Generator Block Diagram: Marker Generator - The sweep generator provides a visual display of the characteristics of the circuit or amplifier, but this is inadequate because it does not…
