## Draw the output voltage waveform for firing angle of =150

this formula is for RMS... can you drawing the output voltage? Hi Oops ! sorry yeah you're absolutely right i wanted to write RMS but my typo . Anyway , average formula is this : 1/T integral over Vs dt from zero up to firing angel . Good luck Goldsmith

## Photodiode Fast detection !!!!

Avalanche operation with zero bias is like mountaineering on the sea. Good luck! :smile: Besides specified bias, a suitable load, e.g. 50 ohm resistor (passive) or TIA (active), is required.

## zero cross detector circuit

how to make a zero crossing detector circuit using 8051

Hi, all I want design a Return to zero optical link with variable duty cycle. I started it from 50% duty cycle. Following is my block diagram. Basically, I use a and gate to generate 50% duty cycle Return to zero(RZ) signal and use D flip flop to recover the signal to Non-Return-zero.

## matlab help about blind channel estimation for MIMO OFDM

yaa....but look at this way....you are decleared capital J and u r using using small j....where small j will get zero values or junk values....ok Good luck

## can anyone Prove that del square pai is equal to zero.

hey u means ∂^2 π=0 na? then well i dont know the exect derivation but del= partial derivatives... and the pie is a if u go for double derivatives of pie it will be zero only.. that was as per the best of my knowledge... best luck..

## code for zero forcing algorithm

Hi all i need a code for zero forcing algorithm to supress interference plz help Thanks

## Why magnetic field outside the long solenoid is zero?

Magnetic field outside a long solenoid can never be zero. Because a solenoid of finite length will have edges and field will come out. However, if we imagine a straigth solenoid of infonite length or a toroid, it will not have edges from where lines of force can come out. therefore field would be zero outside a toroid or a strigth solenoid of infil

## Assembly layer in P-CAD 2004

Mestere Manole, I don't have installed PCAD for testing but it might work by copying the refdes from silk screen to another unused layer. This is a common way for CADs which don't allow multiple RefDes. It works in Eagle. What is zero point ? good luck, melc codobelc

## code for counting pulses from zero crossing detector

Hi, If you are talking about power line zero crossing, then have a look at microchip application note AN958, you will find the answer there. Good luck.

## zero crossing detector circuit

Here are some other examples of zero crossing detectors .. Regards, IanP

## How can I drive a weak zero in Verilog?

Give here ur VHDL example for weak zero. I will write equivalent verilog for that!

## Zero of a common source amplifier

The descprepancy might originate from your hand calculation is not accurate enough: the Cgd of the input transistor is not easily calculated by hand. You should rely on the simulator to give you more precise number. A sanity check also reveals that the zero can not be at over 100GHz frequency. 40~50 GHz is a more reasonable number. Willy
