design production

one

An arbitrary waveform generator that can generate sine waves, square waves, and triangle waves.

The waveform generator can

one

Ensure constant voltage output within a certain range.

2. Requirements

1. Basic requirements

(1) The waveform generator can generate three periodic signals: sine wave, square wave, and triangle wave;

(2) The frequency range of the output waveform is 100Hz

100kHz; frequency adjustable, frequency step interval ≤

100Hz;

(3) Under 50Ω load condition, the output voltage peak

Maximum peak value ≥ 2V;

(4) Function to display the type, repetition frequency (period) and amplitude of the output waveform;

(5) There is no obvious distortion when observed with an oscilloscope.

play part

(1) The frequency range of sinusoidal signals is extended to 1Hz

Step-up square wave and triangle wave output

output frequency.

(2) With output frequency and frequency step setting functions;

(3) Under 50Ω load condition, the output voltage peak

Maximum peak value ≥5V;

(4) It has the function of displaying waveform type, frequency and amplitude;

(5) Can output at least

one

an arbitrary waveform.

3. Description

1. The basic frequency adjustment method can be analog or digital to give full play to partial frequency adjustment.

Can only be numeric.

2. To use some output frequencies and frequency steps, you need to use the keyboard to set them.

3. The type of arbitrary waveform can be selected and the frequency can be changed.

Why is the voltage range of the BUCK circuit always 0-7.2V?
I soldered a simple buck circuit, the power supply is 15V, the capacitor is 280UH, the voltage is 1000uf, the load is 50 ohms, the duty cycle is 97%, the power supply is 15V, but the voltage across th
Phase-locked frequency multiplication design of CD4046
I want to multiply the industrial frequency by 256. I would like to ask whether the center frequency of CD4046 refers to the industrial frequency or the frequency after multiplication. How should the
2440 I2S AD conversion problem
Can I use the I2S audio decoder chip to perform ADC conversion and then send it back to the 2440 processor through the I2S interface? How to do it? The audio chip AK4554 has its own I2S interface and
How to modify the IP address of WINCE in EVC?
I followed the methods on the Internet to modify the IP address, but it always fails. Although the program is executed successfully and the registry key is added, why does it always fail? The method I
How does circuit design determine the resistance value of the current limiting resistor?
Dear experts, when designing circuit schematics, two integrated chips are often connected with resistors in series rather than directly connected. How do you determine the resistance value of these cu
Why doesn’t the new Xiaomi use QC4 low-voltage fast charging?
