@KlausST @barry I would Like to delay the Clock signal (S/H Control) not the Input analog signal.
Analog signal is also delayed however as a result of delaying the clock signal.
Here is a photo to demonstrate what I am trying to do.
The only reply that's considered a solution for my problem is...
Hello ,
I am trying to implement a module that delays the clock of the sample and hold amplifier by one cycle in order to achieve the signals as in the following photo,
The photo on the left shows a rectified signal and a single sampled signal with a clock.
The photo on the right shows the...
Thank you all , I have decided to use STM32 MCU with an ADC input for Frequency tune and SPI Communication with AD9833 to generate the Sine wave.
This solution is similar to Dana's Solution.
I would like to thank everybody for their solutions
Hello,
I have a VCO circuit based on 4046 IC that generates TTL that varies with input voltage.
I would like to convert this variable frequency signal to sine wave with fixed amplitude (Bandwidth less than 1MHz).
I tried using an RC or LC filter however , the amplitude varies with the frequency...
Hello ,
I would like to make bipolar encoding using microcontroller STM32 , I have 2 states only 1 and 0 ,
What hardware can be used to generate this signal with the MCU , is there an IC or should I build a circuit ?
Here is a link for the waveforms that I desire to generate...
Hello , I would like to design a high voltage attenuator that attenuates a signal from 1000Vpeak to full scale of 250mVpeak in order to be suitable for an Isolation amplifier IC
The input capacitance of the IC is around 4 pF therefore , if I used only a resistive divider (Clearly with a high...
Hello ,
I am designing a circuit for controlling the phase angle (Firing angle) of a TRIAC. I don't want to use a microcontroller.
I am have a circuit that generates a PWM signal. I want to design a circuit that introduces a variable phase shift to this PWM signal from 0 to 180 degrees for...
Hello , I am trying to understand how does CVSD Modulator works. The block diagram of the CVSD is below , I understand that the overload algorithm detects whether the previous 3 bits of the modulated signal are all 1s or all zeros. and based on this signal is controls the charging or discharging...
Hello ,
I am testing a PCB for a three phase inverter it's mainly based on the circuit in the following photo
I am using Isolated DC to DC converter to isolate the VDD from the VCC.
My DC-Link voltage is 24V in a dual configuration +/- 12V
I am using an STM32 MCU to generate the PWM signal...
I f
I found the perfect solution finally , its actually more simple than your suggestions.
I will use an Analog multiplier and both its input will be my 1KHz signal so the output signal will a square of the input and the frequency will be doubled It will be having an offset , a phase shift and...
Hello Everyone,
I would like to know if there is an IC or a converter that takes as input Sinusoidal 1k Hz signal and multiplies the frequency to be 2kHz frequency ?
I have a system that features only 1 channel function generator and I need 2 signals so I need a solution for either upconverting...
Hi ,
I have am sort of noob in trasformers. I just know the basics. Today I came by pulsed transformer that work in high frequencies. i read that this type of transformer usually works as an isolation/couplting for gate drives. My question is if I Varied the number of turns of this type of...
Thank you that's very helpful. Now I understand how to calculate the angle from the output sine and cosine signals.
I have 1 more question please. One step backward What's the relation between the reference voltage and the output sine and cosine waves? I thought that the reference voltage is the...
Hi all
I have been studying resolver of Motors lately , I understand the basics that there is a reference signal that is used to excite the resolver and then the resolver produces a sine and cosine signals whose amplitudes are proportional to the angle of the motor.
My question is why do we need...
