Define Time-Shifting Precedes Time-Reversing and Vice Versa
Signal x[n] is time-shifted by m samples (delay in time) giving x[n - m]. This signal is then reversed at n = 0 giving x [- n - m].
Order 2: Time-Reversing Precedes Time-Shifting
Signal x[n] is time-reversed at n = 0 giving x[-n]. This signal is then shifted by -m samples (advance in time) giving x[-[n + m]] or x[-n - m].
Q. What is the function of CT and P.T and where they are used? Ans: The full form of CT is Current transformer and is used for calculating of current. The full form of PT is
a single phase is supplied with sinusoid voltage v(t)=200cos(377t).the resulting instantaneous power is p(t)=800+1000cos(754t-36.7). find
In a CDMA system, the signal is spread over a large bandwidth by multiplying the transmitted symbol by a sequence of short pulses, also called chips. The
Digital circuits In analog circuits, we think something about voltages on terminals ranging over natural values. This provides us the freedom to make an enormous variety
