The microprocessor-controlled oscillator has a frequency range of 8159 to 1, covering from 2 Hz to 20 kHz. An exponential, current output integrated circuit digital-to-analog converter (DAC) functions as a programmable current source, alternately charging and discharging a capacitor...
The power supply is integrated into the base of the microphone, which may cause hum issues, even with the onboard potentiometer designed to nullify this effect. Consequently, the microphone features two cables: one for power and another for audio...
This SCADA controller is designed for use with distribution (13.2 kV/4.8 kV) substation transformer breaker positions where an automatic throw-over is present. The RTU voltage is 24V DC. The breaker status and lockout relays operate at 48V DC. The SCADA...
This is a minimal circuit designed for individual audio amplifier projects to control the presenter output relay. The purpose of this circuit is to manage the relay that activates the speaker output within the audio amplifier. The circuit introduces...
This figure illustrates a block diagram of modern automated systems that incorporate closed-loop feedback for motion control. These systems typically feature a servo system consisting of feedback elements and a motor driver, which work together to provide accurate and...
The add-on circuit presented here is useful for stereo systems. This circuit has provisions for connecting stereo outputs from four different sources or channels as inputs, with only one of them selected and connected to the output at any...
