Assume a 4.094 mhz clock is used as the system clock and the systick selects it as the clock. What should the systick_load regis
Anarel [89]

The load value for interrupts every one milliseconds is

\begin{aligned}&\mathrm{val}=1 \times 10^{-3} \times 4.094 \times 10^6 \\&\Rightarrow \mathrm{val}=4094\end{aligned}

The load value for interrupts every millisecond is

\begin{aligned}&\mathrm{val}=1 \times 10^{-6} \times 4.094 \times 10^6 \\&\Rightarrow \mathrm{val}=4.094\end{aligned}

However, we can only load integer values, therefore we apply

\Rightarrow v a l \approx 4

When the delay is 1 ms, it is accurate, but when the delay is 1 us, it is a little bit less. We are unable to provide an accurate 1 us delay interrupt because this requires a fractional value was calculated.

<h3>What does a SysTick timer do?</h3>
  • The systick timer has an auto reload and a 24-bit countdown timer.
  • An RTOS scheduler typically uses it to provide a periodic interrupt.
  • The Cortex-M CPU clock is used as the default clock source for the systick timer.

Two in-phase loudspeakers that emit sound with the same frequency are placed along a wall and are separated by a distance of 8.0
zloy xaker [14]

Answer: 278\ Hz

Explanation:

Given

Distance between two speakers is 8 m

Man is standing 12 away from the wall

When the person moves 3 parallel to the wall

the parallel distances from the speaker become 4+3, 4-3

Now, the difference of distances from the speaker is

\Delta d=\sqrt{12^2+(4+3)^2}-\sqrt{12^2-(4-3)^2}\\\Delta d=1.85\ m

Condition for destructive interference is

\Delta d=(2n-1)\dfrac{\lambda }{2}=(2n-1)\dfrac{\nu }{2f}\\\\\Rightarrow f=(2n-1)\dfrac{v}{2\Delta d}

for second destructive interference; n=2

\Rightarrow f=(2\times 2-1)\dfrac{343}{2\times 1.85}=278.10\approx 278\ Hz
