The standard CD, co-developed by Philips and Sony, uses a 16-bit word length and a sampling rate of 44.1kHz).

Pulse Code Modulation. Conversion method for transforming analogue audio samples into their digital equivalent, so that they can be processed by computers, DSP-chips etc. The number of bits to express the amplitude value depends on the required signal to noise (S/N) ratio. For audio CD's, 16 bits are used to represent a sample, resulting in S/N of 96 dB (20*log216). The frequency with which the amplitude is sampled and converted (i.e. the samplerate) is depends desired bandwidth. For audio CD's the samplerate is 44.1 kHz, resulting in a bandwidth of 20 kHz. Standard uncompressed PCM (as used for audio CD's) is also referred to as linear PCM. An often encountered compressed equivalent is ADPCM, which is used for CD-I and CD-ROM XA disks.

Pulse Code Modulation, an encode method of converting an analog signal to digital samples. The encoding can be Linear or Non-Linear (like u-law or A-law weighting). For example, if 8 bit linear PCM is used, 0 Volts could be encoded as 0, and 5 Volts could be encoded as 255 and each step would be 19.6 mV. Then 2.5 Volts would be encoded as 2.5 V / 19.6 mV = 128

Pulse Code Modulation. PCM is how digital audio is typically represented in a computer. The audio signal is represented by samples of its instantaneous amplitude taken at regular intervals (the sample period which is the inverse of the sampling frequency). The representation of each sample can take several forms. On CDs, a 16-bit integer is used. Plain old telephony uses 8 bits with a non-linear coding (either A-law or u-law). Studio equipment often used 24 or more bits. Floating point representation is also possible. Alsa can use the following formats: S8 U8 S16_LE S16_BE U16_LE U16_BE S24_LE S24_BE U24_LE U24_BE S32_LE S32_BE U32_LE U32_BE FLOAT_LE FLOAT_BE FLOAT64_LE FLOAT64_BE IEC958_SUBFRAME_LE IEC958_SUBFRAME_BE MU_LAW A_LAW IMA_ADPCM MPEG GSM SPECIAL S24_3LE S24_3BE U24_3LE U24_3BE S20_3LE S20_3BE U20_3LE U20_3BE S18_3LE S18_3BE U18_3LE Other representations than PCM are possible. For example it is not necessary to have a one-to-one correspondance between the samples of the audio signal and the numbers in the data stream. (Example: mp3)

Stands for Pulse Code Modulation and is a way of digitally encoding data. Specifically it is a system used to record high quality digital audio on to the Betamax video format. The picture if viewed on a television would show black and white dancing around in an almost static interference type pattern. When connected to a PCM unit, this image is converted to a digital audio stream. A number of Betamax units came with a switch at the rear to allow the unit to work more efficiently when recording a digital audio "picture", the switch is used to remove the drop out compensator circuitry on playback to allow the PCM unit to carry out its own error correction on the signal without the player altering the signal. For normal video playback, the should not be switched on. See also the PCM feature for further information.

PCM stands for Pulse Code Modulation and actually is still FM. The difference between PCM and FM is that the control information is sent in the form of a digital data pulse [word] rather than just an analog signal pulse. I suppose you could compare this to your cassette audio tape and an audio CD. FM would be the tape and PCM the CD. Click Circuitry to read more about PCM and radio controls.
