nescaf
The NEScaf filter is designed to offer greater flexibility than previous filters for QRP (low-power) radio rigs. It features two panel-mounted controls: a single center-detent potentiometer that adjusts the center frequency of the filter's bandpass (settable between approximately 415 Hz...
Transformerless Dc -To- Symmetric DC Converter
A DC to DC converter is required for a circuit board that operates solely on a +5V supply but needs to deliver dual-polarity outputs for several devices, such as operational amplifiers (op-amps) and digital-to-analog converters (DACs).
To achieve dual-polarity supplies, a...
Simple Audio Filter Analyzer Circuit
When this circuit is connected to a filter and an oscilloscope, the oscilloscope displays the filter's frequency response. A frequency that sweeps from low to high is applied to a filter. The oscilloscope is triggered by the start of the...
KC2ZPLs Web Design and Electronic Home
Now that these power supplies are available, it would be beneficial to evaluate their performance. Traditionally, an adjustable load (a robust resistor) is connected to the output to measure both output voltage and current at various points. This allows for...
Half-wave rectifier
The circuit enables precise half-wave rectification of the incoming signal. It exhibits a gain of 0 for positive signals and a gain of -1 for negative signals. By reversing both diodes, the polarity can be inverted. While this circuit delivers...
Circuit diagrams and Schematic
This AC to DC power supply can output 5A in continuous operation and 12A peak current. This type of DC power supply uses a PCB, allowing for two case types for IC1: TO-220 or TO-3. The regulation of this 12-volt...
Sony KV-S29MHl TV switching power supply (SIR a 80145A) circuit diagram
The circuit of the Sony KV-S29MHl (S Movement series) TV switching power supply (SIR a 80145A) consists of three main sections: (A) the power oscillation part, (B) the regulator part, and (C) the output section.
The Sony KV-S29MHl TV switching power...
DC to DC Converter
The intended use of the 24 volts is to power an amplifier that will supply wave forms of up to a couple hundred Hz to bias a varactor or pair of varactors in an RF circuit. This meant that the...
diode bridge rectifier circuits
A rectifier is an electronic circuit that converts AC voltage to DC voltage. It can be implemented using a combination of capacitors and diodes. The unique property of diodes, which allows current to flow in a single direction, is utilized...
