    verilog code correction???

    can you modify it ? I'm new to verilog.And if i am changing all the blocking assignments to non-blocking results are not right because of this part i thinktemp=current; current=current+previous; previous=temp;.Thankyou

    verilog code correction???

    can anyone please tell me if there is any logical error is this always block,its for fibonacci series ,i'm getting my results right but i was just curious if i've done something which isn't correct like using two 'if's? always@(posedge clock) begin if(n==0) current=1; else...

    transfer function,s-domain

    Thanks a lot !That cleared my confusion a lot. That's the lecture slides that my professor provided us with.Slide 21 is where this topic starts.And i still have the confusion about where did the equation of H(jw) came from originally lol but the confusion about the transformation to s-domain...

    transfer function,s-domain

    I still don't get it :( ,i get how we wrote sz in place of wz but then what about the s in numerator,don't we require another j for it ,so we could write s in place of jw ? Thanks a lot :)

    transfer function,s-domain

    you got the question incorrectly,it isn't w*z its wz which is the zero of a circuit.I've attached the image for your convenience.

    transfer function,s-domain

    How this is H(w)=1+jw/wz equal to H(s)=1-s/sz where sz=-jwz?? I can't seem to prove that :/

    Question related to Moore's Law

    I need to solve this question ,I am not sure if i'm solving it right q:In 1972, Intel 8008 microprocessor had 3500 transistors manufactured in 10 µm process while in 2006, Intel Itanium 2 processor contained 1.72 billion transistors using 90 nm process. Based upon these two data points only and...
