Test Signal Generator
This signal generator uses a three channel DAC to generate Composite video signal (CVBS) and S video signal (Y/C separated) at the same time, left one channel is not used in NTSC format. It is assigned for one of the...
Audio Oscillator
Two gates, U1A and U1B, of a 4049 hex inverter, are connected in a VFO circuit. Components R1, R3, and C1 set the frequency range of the VFO. With the given values, the circuit's output can range from a few...
Precision Metronome/Pitch
Precision Frequency generator 1 to 999 Hz Precision Metronome 1 to 999 beats per minute. CMos IC1 and IC2B quad AND gate form a 2.4576 MHz crystal oscillator plus a 2400 times divider. IC3A provides further division by 16, delivering...
sine wave to ttl converter
The current circuit is designed to convert sinusoidal input signals into TTL output signals. It is capable of handling input signals greater than 100 mV and operates effectively at frequencies up to approximately 80 MHz. Transistor T1 is configured in...
Sine wave oscillator II
In this circuit the gain is provided by a FET type op-amp. I have used an LF351, which may be hard to obtain, but the TL071CN or TL081CN may be used and have a faster slewing rate than the LF351....
1KHZ Sine Wave Generator Circuit
Set R5 to read 1V RMS on an audio millivoltmeter connected to the output with R7 rotated fully clockwise, or to view a sine wave of 2.828V peak-to-peak amplitude on the oscilloscope. An audio amplifier is an electronic device that...
Oscillator
A tone generator operates on as little as 1.5 VDC using the Sallen-Key configuration. The tone generator will be applied to implement a phantom-powered signal source for testing balanced microphone inputs. Textbooks and web pages typically depict the Wien Bridge...
Generating a simple sine wave
A sine wave carrier is required for a magnetic transponder system. Various crystal-based oscillators, such as the Pierce oscillator, can be complex to design and ensure proper functionality. An alternative approach involves using a square wave oscillator in conjunction with...
Auto Shut Off Tone Generator
In this auto shut-off tone generator project, connecting the switch to the 9V power supply triggers an alarm that emits a frequency of approximately 1.27 kHz. The alarm remains active for about 170 seconds (or 2.8 minutes) before it stops....
