   a 1 kHZ signal is flatop sampled  at the rate of 1800 samples sec and 


samples are applided   to an ideal rectangular LPF with cutoff frequency 


of 1100 hz then the output of filter contains  


(a)  only 800 Hz components  


(b)  800Hz and 900 Hz components  


(c)  800Hz and 1000 Hz components  


(d)  800Hz,  900Hz and 1000 Hz components


 A series LCR ckt consist of R=10 ohm,X =20 ohm is connected across an 


AC supply of  20v rms the rms voltage the capacitor is  


(a)  200<90degree v  


(b)  200<-90degree v  


(c)  400<90degree v  


(d)  400<-90degree v
