Answer: None; all will be recoverable
Explanation:
If a signal (band-limited) is sampled at regular intervals, it could be recoverable or not, based on the number of samples taken.
Let's assume that we want to take samples of a simple sinusoid; If we take more than two samples during a signal cycle, the original waveform will be able to be reconstructed, just passing the sampled waveform through a low-pass filter.
In the more general case in which the signal occupies a frequency spectrum, if the sample frequency is greater than the double of the highest frequency in the spectrum, the signal can be retrieved completely, according to the Nyquist Theorem.
In this case , as the highest frequency is 145 Hz, it would be enough to take samples at a rate greater than 290 Hz; As the sample rate is 295 Hz, all the signal can be recovered, at least, using an ideal "brickwall" low-pass filter.
Answer:
For security and privacy reasons, it is best to use the Blind Carbon Copy (BCC) feature when sending an email message to a large number of people. When you place email addresses in the BCC field of a message, those addresses are invisible to the recipients of the email.
