Magnetic pickup pre-amplifier circuit
A preamplifier for magnetic pickups of record players is presented. The uA 741 is utilized as an AC-coupled non-inverting amplifier operating on a single supply. The amplifier gain is determined by the feedback components, where C2 manages the low-frequency roll-off...
One Receiver
RF Cafe visitor David M. requested the scanning and posting of an article from the January 1963 edition of Popular Electronics, authored by Philip Hatfield from the Receiving Tube Department of General Electric. The article describes a straightforward design utilizing...
Wireless/Wii Hack for SNES and NES Controllers
The NES version of this modification closely resembles the SNES version, and it is advisable to review that article first for a general understanding of the assembly of these controllers. The primary component required is an original NES controller, which...
Precision polarity switching circuit by conventional elements
The loop gain of the operational amplifier (OP) is primarily influenced by the ratio of the input resistor to the feedback resistor. Consequently, any resistance error can lead to a corresponding gain error, which necessitates the use of high-precision resistors,...
2ChPre
A dual-channel audio preamplifier designed to be an optimal preamplifier for the high-quality Audio Analog to Digital Converter AD24QS. The aim was not to create a smaller or cheaper preamplifier with similar functionality, but rather to develop a superior product....
10Mhz coaxial line driver
The circuit is ideal for high-frequency line driving systems that necessitate a wide power bandwidth at elevated output current levels. The integrated circuit used is HA2530. The bandwidth of the circuit is constrained solely by the single pole response of...
Active-limiting-amplifier
The modified inverting amplifier employs an active clamp to precisely limit the output swing. Consideration must be given to the VBE of the transistors. The output swing is restricted by the base-emitter breakdown of the transistors. A straightforward circuit configuration...
Band decoder circuit diagram
The circuit amplifier and attenuator control video detector consists of a composition for the synchronization channel. The synchronization interval is where the gain circuit is increased.
The described circuit involves an amplifier and an attenuator that work together to control a...
Wideband Display
This is the construction guide for the 5301 wideband fuel mixture display kit. The 5301 is the Tech Edge version (rather than the Jaycar version) of the modified Silicon Chip FMD design, and it features, compared to the original kit,...
