a transmitter is operating at 150 MHz with a power of 3 W into a one-quarter wavelength vertical antenna. The receiver, which is 32.2 km away, has an antenna with a gain of 8 dB. What is the received power?
The received power will be 1.243 nW
We're given:
frequency [tex]f[/tex] = 150MHz
distance of the receiver [tex]d[/tex] = 32.2 km=32200m
Power of transmitter [tex]P_{t}[/tex] = 3W
Antenna gain = 8dB
To find :
Power received [tex]P_{r}[/tex]
[tex]P_{r}= \frac{P_{t} *G_{t}*G_{r}* \lambda^2 }{16*\pi^2*d^2}[/tex]
where [tex]G_{t[/tex] is transmit gain and [tex]G_{r[/tex] is receive gain as refrenced to isotropic source
⇒wavelength [tex]\lambda = \frac{c}{f}[/tex] where c is the speed of the light
⇒ [tex]\lambda = \frac{3*10^8}{150*10^6} =2m[/tex]
[tex]G_{t}= 1*1.64[/tex] ( value of [tex]dipole[/tex] = 1.64)
Now,
Antenna gain[tex]=8dB[/tex] ( in decibals)
⇒[tex]10log(x)=8[/tex]
⇒[tex]x=10^0^.^8=6.3095[/tex]
⇒ considering isotropic receiver
⇒[tex]G_{r}=6.3095*1.64=10.3477[/tex] ([tex]dipole[/tex] =1.64)
Now , using the formula
[tex]P_{r}= \frac{3 *1.64*10.3477 *2^2 }{16*\pi^2*32200^2}=1.2437*10^-^9[/tex]
Hence The received power will be 1.243 nW

Explain how cache (SRAM) can support CPU pipelining.
Answer:
The Pipeline Burst Cache is basically a storage area for a processor that is designed to be read from or written to in a pipelined succession of four data transfers. As the name suggests 'pipelining', the transfers after the first transfer happen before the first transfer has arrived at the processor.

If the 294.00 units are made and the cost per unit is $2.25 then variable expenses for the day is $661.5.
Given that 294.00 units are made and the variable cost per unit is $2.25
We have to find variable expenses for the day.
Total variable expenses for the day are a product of the output and the variable cost per unit.
So the variable expenses = no. of output x variable cost per unit
Variable expenses = 294 x 2.25
Variable expenses = 661.5
