Do Oscillation Building Circuit by Your Self!
An oscillator is a mechanical or electronic device that operates based on the principles of oscillation. Oscillators serve as fundamental building blocks upon which the entire structure of electronics and computers is established. An article is available that explains how...
Questions about colpitts oscillator design
The input and output impedance, along with load and source resistance, are significantly interdependent in a common collector (CC) circuit. This interdependence is why impedance matching does not yield representative results for circuit operation. Analyzing the circuit as a common...
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...
Variable Duty-Cycle Oscillator Circuit
A 1.2-kHz oscillator utilizing a potentiometer and steering diodes allows for a duty cycle adjustment ranging from 1% to 99%. The frequency can be altered by varying the capacitor CI. It is important to note that the diodes may slightly...
Metal detector circuit diagram 8
The metal detector circuit consists of a probe oscillator, a PLL (phase-locked loop) circuit, and an audio alarm circuit. The probe oscillator includes a detection coil (L), transistor (V1), and several resistors (R1 to R3) and capacitors (C1 to C5)....
Amp Gain Block
The feedback in this circuit is DC coupled, connecting directly from the plate of the second triode to the cathode of the first triode, as opposed to the earlier design which utilized AC coupled feedback. The previous version exhibited instability...
Metallic pipe detector
This circuit employs a 15-kHz oscillator coil. When metal is removed from the energy field, the oscillator voltage is rectified and compared to a reference. A decrease in oscillator voltage activates comparator IC2, causing D4 (LED) to turn off.
L1 consists...
