Hello ,
I need to connect the ARM STM32F2 with array of fast counters.
Counters will put into FPGA Spartan III.
Looking for a sample project in which it was joined by ARM and FPGA, your advice ?
I am particularly concerned about the interface between MCU and FPGA, do not go for anything fast...
I know that it is me is more about what makes a 1000uF capacitor, which will pass high frequency, 1MHz, but also 100MHz.
What will be the effect on C passing frequency (sine wave), it will act as a capacitor antenna
You're right, I chose the example of inappropriately.
Say that the frequency will be 300MHz, 1/4 wavelength is 25cm and and is a measurement application, therefore it is necessary to take into account that the sinus has the largest voltage change during the first 10% of the sinusoid.
A few beginner questions.
1. If we lead the signal from 50 ohm source to 50 ohm load is a good line to PCB design with 50ohm impedance as microstrip line. How will solve the line on PCB in the case where source is operation amplifier and load have impedance 1000 Ohm?
2.If we had two...
Hello,
I have amplifier say AD8021, amplifier work to 50ohm load, frequency 100Hz-1MHz, Gain=10, output amplitude +- 2,5V. AD8021 have input offset 1mV
I need remove DC offset, question is how?
I think add on output capacitor or more precisely several capacitors parallel.
Question is what to...
