WebElectrical Engineering. Electrical Engineering questions and answers. Q.1. We have sampled a low-pass signal with a bandwidth of 200 KHz using 1024 levels of quantization. Calculate the bit rate of the digitized signal. Q.2. What is the Nyquist sampling rate for each of the following signals? a. WebNov 24, 2024 · The bandwidth of an input signal to the PCM is restricted to 4 kHz. The input signal varies in amplitude from – 3.8 V to + 3.8 V and has the average power of 30mW. The required signal to noise ratio is given as 20 dB. The PCM modulator produces binary output. Assuming uniform quantization,
5 5 we have a channel with 8 khz bandwidth if we want - Course …
WebSep 2, 2024 · The closer the sampling frequency gets to twice signal bandwidth, the longer time is required of the sampled signal. It’s something like : if you oversample by 1% (that is sample rate = 2.02 * bandwidth) then you need something like 100 periods to reconstruct with something like 1% SNR. WebMar 17, 2024 · However, with audio components, the SNR is always a positive value. For example, an SNR of 95 dB, means that the level of the audio signal is 95 dB higher than the level of the noise. Which, in turn, means that an SNR of 95 dB is better than one that is 80 dB.

WebBandwidth is related to no. of samples per second. In PCM, we send the information in binary (0, 1), if we treat each bit as a sample and we transmit samples or bits then … WebFor a minimum bit rate, the modulating signal must be sampled at the minimum sampling rate, i.e. at the Nyquist Rate. f s = 2f m. f m = Maximum frequency present at the … WebMar 17, 2024 · However, with audio components, the SNR is always a positive value.
