Question
Assume the sampling rate is 20000 Hz, sinusoid signal frequency is 1000 Hz. Calculate the zero crossing value for 100. Choose correct option from the following:Select one:a. 200b. 10c. 20d. 100
Solution
The zero crossing rate is the rate at which a signal changes from positive to negative or back. This is a common feature used in many areas of speech and audio processing.
To calculate the zero crossing rate, we need to know the frequency of the signal and the sampling rate.
In this case, the frequency of the sinusoid signal is 1000 Hz and the sampling rate is 20000 Hz.
The zero crossing rate is calculated as follows:
Zero crossing rate = Frequency of the signal / Sampling rate
So,
Zero crossing rate = 1000 Hz / 20000 Hz = 0.05
But we need to find the zero crossing value for 100. So, we multiply the zero crossing rate by 100:
Zero crossing value = Zero crossing rate * 100 = 0.05 * 100 = 5
However, this value is not in the options provided. There might be a mistake in the question or the options provided.
