Crystal Sine Wave Oscillators
In applications where good frequency stability is essential, such as radio transmitters, basic LC oscillators may not maintain their frequency without drifting. This drift can be caused by small changes in supply voltage, although stabilized power supplies can help mitigate...
Automatic Dual Output Display
This circuit sequentially lights ten bulbs, first in one direction and then in the opposite direction, creating an appealing visual effect. Gates N1 and N2 form an oscillator, which serves as a clock for the BCD up/down counter CD4510 (IC2)....
The door bell circuit
Figure 1 illustrates an economical and straightforward Gate Alarm designed to operate using a small universal AC-DC power supply. IC1a functions as a fast oscillator, while IC1b serves as a slow oscillator. These two oscillators are integrated through IC1c to...
Metal detector circuit diagram 1
The metal detector circuit includes a fixed frequency oscillator, mixer, detector, detection oscillator, and power amplifier circuit. The fixed frequency oscillator circuit is composed of a ceramic filter (ZC), transistor (V1), resistors (R1 to R4), capacitor (C2), and other components....
1KHz Sine wave Generator
This circuit generates a good 1KHz sinewave adopting the inverted Wien bridge configuration (C1-R3 & C2-R4). It features a variable output, low distortion and low output impedance in order to obtain good overload capability. A small filament bulb ensures a...
Metal detector 4
The metal detector circuit comprises a detection oscillator, a reference oscillator, a mixer, and a signal display, as illustrated in Figure 8-70. The detection oscillator circuit is made up of the time base oscillator IC1, inductor L1, potentiometer RP1, diode...
SINE WAVE TO SQUARE WAVE CONVERTER
The sine input is AC coupled by capacitor C. Resistors R1 and R2 bias the input midway between Vn and Vp, the input threshold voltages, to provide a square wave at the output.
The circuit described utilizes an AC coupling technique...
square wave oscillator circuit
A simple square wave oscillator can be created using two gates from a CMOS 4011 NAND chip. Alternatively, a CMOS 4001 chip or a TTL equivalent can also be utilized. In this circuit, the mark-space ratio can be independently controlled...
Electronic Organ Circuit
This electronic organ circuit is straightforward to construct and primarily consists of an emitter-coupled oscillator formed by transistors T2 and T3. A square wave voltage can be obtained from the collector of T3 (X2), which imparts a clarinet-like quality to...
