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…
BCD Subtraction: Addition of signed BCD numbers can be performed by using 9's or 10's complement methods. A negative BCD number can be expressed by taking the 9's or 10's…
RC Phase Shift Oscillator Using Op amp: RC Phase Shift Oscillator basically consists of an amplifier and a feedback network consisting of resistors and capacitors arranged in ladder fashion. Hence…
Summing Amplifier: As the input impedance of an op-amp is extremely large, more than one input signal can be applied to the inverting amplifier. Such circuit gives the addition of…
